The largest trailwork event in the Santa Monica Mountains is held every year at the end of April in Pt. Mugu State Park. This past weekend, volunteers from CORBA, the Santa Monica Mountains Trails Council (who organize the event every year), the Sierra Club and others converged on the Danielson campground to help out. Besides trailwork on Saturday and Sunday, the festivities included a barbecue dinner, a huge prize give-away and optional overnight camping.
Clearing mustard on the Sin Nombre Trail
On Saturday morning, 140 volunteers split up into crews of about 10 and dispersed to various trails. The crew that included most of CORBA’s volunteers shuttled to the top of the Sin Nombre Trail and started the day by cutting back mustard that was crowding the trail. When that was finished, we worked our way south, spending our time fixing deep ruts. That involved cutting down the berm that forms on the outside of the trail and dragging the dirt back into the rut, and also building up the inside of the trail to restore a gentle outslope. The outslope allows water to run off the outside of the trail, rather than running down it and eroding a new rut.
Fixing a rut on the Sin Nombre Trail
The north end of the Sin Nombre trail is very rocky in sections, so it took a considerable amount of work to restore the trail to it’s original condition.
While the CORBA crew was working southward, two other crews were working north from the bottom of the trail. They also were fixing ruts.
After lunch on the trail, a few from the other crews came up to help the CORBA crew. The extra hands allowed us to finish our work an hour early – the help was very much appreciated! With three crews working, we were able to repair all of the ruts along the length of Sin Nombre that were repairable.
Fixing the tight, rocky switchback at the bottom of the Wood Canyon Vista Trail, part of the Backbone Trail.
A crew consisting of mostly MBU members and led by Steve Messer, CORBA’s president, worked their way up the Wood Canyon Vista Trail. They started by rebuilding the first very tight switchback which had become rocky and difficult to navigate in recent years. When that was done, they headed up the hill to generally clean out old drains and build new ones where needed.
Other crews worked on Sage Trail, rebuilding walls and drainages, Old Boney Trail near Sorreno Valley in the Boney Mountain Wilderness Area, and a group of youngsters and their parents cleared brush from the side of the Blue Canyon Trail. Building Bridges to the Outdoors Sierra Club worked on Coyote Trail.
Decorating the dessert cakes for Saturday’s dinner
There hasn’t been any rain recently so the dirt was bone-dry and turns to dust when we dig into it. Because of this, it’s not possible to pack it down firmly despite our best efforts. Be careful when riding these newly worked trails – parts of them are pretty loose still!
Saturday afternoon was spent relaxing around camp, chatting with friends and rehydrating, often with light- to dark-brown beverages. Some people went hiking or riding and youngsters helped decorate the desert cakes with colored icing and sprinkles.
The barbecue dinner, cooked and served by Park staff, was fabulous as always – barbecued tri-tip, chicken and veggie burgers along with salad, garlic toast and baked beans. During dinner, Tony Hoffman from State Parks, along with a pair of young volunteers, called ticket numbers for the prize give-away. The very best prizes (tents, sleeping bags and such) were gone by the time this correspondent’s number was called; even so I got a gift certificate to a nice restaurant in Thousand Oaks that I like.
David Szymanski, superintendent of the Santa Monica Mountains National Recreation Area, and Craig Sap, superintendent of State Parks Angeles District dropped in during the afternoon and dinner to chat and thank the volunteers for all their help.
After it got dark, slide shows were given by State Park scientists on the archeology of the area, especially with respect to mudslides over hundreds of years and their effect on native inhabitants, and the ecology of recovery after the Springs Fire two years ago.
Saturday night barbecue dinner and prize give-away
The number of volunteers for Sunday’s trailwork was much smaller, as happens every year. Two dozen people broke into three crews; one worked on “Toe-stubber” a second continued clearing overgrowth from the Blue Canyon Trail, and the kids did some easy trail smoothing nearby with their parents.
CORBA would like to thank all the volunteers and Park staff who made this year’s event a rousing success!
On Sunday, April 17, 2016, 32 volunteers converged on the Windsor/Ventura parking area, the Gabrielino trailhead, in Altadena. The day, hosted by our partners at the Mount Wilson Bicycling Association, was a complete success by all measures. It was our last scheduled group trailwork day on this restoration project, which began in earnest last Fall. In October last year, I declared that all these tools we were hauling up to the top of Brown Mountain would not be coming back down Brown Mountain. They’d be going out the bottom of the trail and the Gabrielino, once the trail was finished. Last Sunday, the tools were brought out of the bottom, as planned.
In reality, the project started long before last fall. In 2013, we scouted the Gabrielino trail north of Paul Little campground, up to Oakwilde campground and the Ken Burton trail. The trail was devastated, with two major slides (think hundreds of cubic yards of earth sliding off the mountain and taking the trail with it). Before we could work on the Ken Burton trail, we had to complete the Gabrielino trail to which it connects, otherwise the two trails would be dead-ends. So our first task was to restore the Gabrielino, up and over the Brown Mountain Dam to Oakwilde/Ken Burton trail.
While our experienced volunteers could tackle the project, we were much more confident having a professional take care of it. At the same time, the Los Angeles Conservation Corps signed a contract with the Forest Service to work on the Gabrielino trail. They didn’t feel comfortable repairing some of the major damage either.
CORBA applied for and received a generous grant from REI for this section of the project. We applied that grant primarily to pay professional trailbuilders Bellfree Contractors for their expertise and work with the LACC. That work required Forest Service engineers to inspect and approve the work plan, the removal of chainlink fencing, and the re-routing of two sections of trail to avoid the major slides.
Over winter 2014-2015, the work was completed by Bellfree and the LACC. They discovered the original trail alignment near Oakwilde Campground, a fully-benched trail segment 30 or more feet above the stream bed on the eastern side slope of the creek. There were sections of rock and cement retaining wall that we estimate were built as a part of the Gabrielino in the 1950s. The LACC and Bellfree restored the trail through that section, rather rebuilding it along the streambed that everyone had been using before the Station Fire.
This segment of trail was completed last winter, but the Forest Service wouldn’t open it to the public as it was a dead-end, and too many people had already been rescued trying to find their way through the Arroyo. The completion of that section allowed us to ask permission from the Forest Service to begin on Ken Burton trail.
Oakwilde campground was devastated, and was buried under 3 feet or more of silt and sediment as the Arroyo Seco swelled well above its banks, bringing with it all the dirt and sediment from the naked hills after the station Fire. Only the tops of the picnic tables, now a few inches above “ground”, are all that remain in the campground. We’re hoping the campground can be restored to a primitive hike-in backcountry camp in the future.
So while we’ve been working on the Ken Burton for just six months, more than two years of planning and pre-requisite projects have needed to take place.
Last Sunday we had a long list of tasks to finish Ken Burton trail. With so many volunteers to help, we completed: the complete rebuilding of three switchacks; widened and cleaned up three additional switchbacks; re-cut bench on a quarter mile of trail; rock-armored two switchbacks; installed a half-dozen drains; rock-armored and rebuilt two major washed out drainages; cleared brush from the upper trail that had grown in since we worked on it six months ago; and cleared additional brush and poison oak near the bottom, all on the Ken Burton trail.
Installing rock retaining walls on the Gabrielino trail
A finished rock retaining wall on the Gabrielino
With the additional manpower, we also installed two rock retaining walls, and widened two sketchy segments of the newly re-established route of the Gabrielino trail, just south of Ken Burton. That segment will be a part of the Brown/Burton/Gabrielino trail loop, and was an important project to complete for us to feel comfortable with the trail being opened to the public.
Walk-through of our day’s work
What the bottom section looked like before our work
While working, several mountain bikers and a couple of trail runners came through the trail. It’s nice to see the trail getting use after being closed for seven years. The trail and switchbacks near the top have packed down and hardened up beautifully, having had a longer time and a lot of traffic from all the volunteers riding and hiking in to work on the lower trail. Many of the switchbacks towards the bottom that are still very loose, having had little to no rain over the past few months as we’ve worked on the trail.
The most defining moment of the day, was when we, with Forest Service authorization, removed the “trail closed” sign from the upper Ken Burton trailhead at the end of Brown Mountain Road. A Forest Service ranger inspected the trail two weeks ago, and recommended the trail be opened to the public, once we completed today’s work. The ranger’s only comment was that the Ken Burton trail “is in way better shape now than many Forest Service trails that are already open to the public.”
Removing the Trail Closed sign
We concur. The trail is in better shape than most of us remember it from before the fire. With the brush not nearly as tall now, there are some incredible views that were blocked before the Station Fire. Eventually the brush will grow taller and obscure the views again, but right now, it can’t be beat. You can see downtown Los Angeles, all the way up the Arroyo Seco canyon, highway 2 and the historic Slide Canyon Bridge.
A rebuilt switchback, still soft.
The trail includes 22 switchbacks that get progressively steeper and more technical as you descend. It’s great practice! But locking up and sliding your back wheel around the turn is not the correct, or the fastest way to ride a switchback. Practice until you can ride without sliding! Until we get another rain and some time for the trail to pack down, we all need to take it easy.
Riding the Arroyo Wash along the Gabrielino Trail
The return ride on the Gabrilieno trail is always an adventure. On Forest Service maps the trail appears as “unmaintained, unimproved, primitive trail.” For about 1.25 miles, you’re riding in the sediment that has been trapped behind the Brown Mountain dam. It can be something of a maze to pick your way through, but as more and more people begin to ride Ken Burton trail, a more defined line will be developed through the arroyo wash. Then with a big rain storm, the stream may change course and we’ll find a new route through the wash.
That’s the beauty of this trail. It really feels like you’re in the backcountry and riding in a wild place.
The trail leaves the wash at a rocky hike-a-bike chute on the right side of the river. It’s marked by ribbons and tire tracks in the sand leading up to it. Eventually we’ll need to improve that section to create a rideable/hikeable ramp out of the wash. But for the moment, prepare for a 50’ hike-a-bike up through the boulders. The trail then meanders through the alluvium, before crossing the stream and beginning the climb up and over Brown Mountain Dam.
At the crest, there are great views of the Brown Mountain Dam from above. The chainlink fence that previously lined that section has been removed, with the materials from the fence being re-purposed as retaining wall structures for segments of the Gabrielino trail. The result is a much more pleasant segment with better views. The trail through this section is extremely loose, with three very loose, tight and steep switchbacks that most people will hike their bikes through. Coming the other direction, they will be a hike-a-bike for most.
The Gabrielino trail remains closed north of Ken Burton Trail junction. This “Trail closed” sign was moved from the top of Ken Burton to here.
Our next project in our ongoing mission to reopen all front country trails will be the completion of the Gabrielino trail through to Switzers and Redbox. Work has been underway on that segment for the past year by the Los Angeles Conservation Corps, but they’re down to a similar situation where the trail is so bad they are going to need professional help. Once again, CORBA has applied for an REI grant to help complete the section. CORBA volunteer chainsaw operators will help clear more than 60 downed trees through that segment of the trail. It may be another year before the Gabrielino is opened all the way through to Switzers.
The effort this has taken is remarkable. We’ve had at least 97 individual volunteers who have given over 1650 volunteer hours, spread over 15 scheduled work days and another 14 prep days with smaller crews. Volunteers have collectively ridden (or hiked/run) over 4000 miles with over 400,000′ of climbing to and from the work site over the past six months. We’ve had volunteers from four high school mountain bike teams participating, and people traveling from as far away as Long Beach, Orange County and Santa Clarita.
Ken Burton
So with the Ken Burton trail reopening, the question has been asked by several people. Who was Ken Burton? The Mount Wilson Bicycling Association did a great history of the trail. It was built from 92 – 95 by the Forest Service and the Mount Wilson Bicycling Association. Ken Burton was a much-loved Forest fire fighter who was struck and killed by a drunk driver near Chilao in 1988. The trail was named in his honor, and a memorial placed at the top of the switchbacks, the section with some of the best views.
While there is still a little fine-tuning to do, we’ll be having an official ribbon-cutting and volunteer recognition on May 1st at Gould Mesa campground, as a part of the Mount Wilson Bicycling Association’s annual Pancake Breakfast. Come out on out, ride the trail before chowing down on delicious pancakes, and check on your chances to win some amazing prizes. Volunteers who did at least two days of volunteer work on the project will be presented with a commemorative T-shirt. It’s the least we could do to thank everyone for such a great effort.
Now go and ride it. We’ve earned it.
Here’s a timeline of progress reports on the project:
We had an unusually poor turnout for our trail restoration project along the Backbone Trail between Kanan and Latigo Canyon Roads. Even so, our small group of five (4 mountain bikers and one trail runner) got a lot done, and along with the dozen or so volunteers from our partners with the Santa Monica Mountains Trails Council, we worked about a mile of trail, starting on the top of the tunnel just past the first steep hill out of the parking area. The poor turnout of mountain bikers was a real disappointment, especially because this is such a great and popular trail for mountain biking. This is the first leg of the ride between Kanan Road and the Corral Canyon trailhead.
Starting to hack back the brush that was overgrowing the inside of this turn.
There were three major problems that we needed to address – lack of drains, poorly constructed drains and overgrowing brush that included a lot of poison oak (PO).
We originally scouted this trail about six weeks ago, but we had to scrub that work day because we learned only a couple of days beforehand that there would be a major event that morning, with hundreds of trail runners passing through the work area, and the parking area would be used by support crew.
We scouted the area again last week to flag the spots where we could be working. In just six weeks the amount of growth of the brush, and especially the PO, amazed us!
For dealing with most of the overgrowth, we left that to the Trails Council crew and their gas hedge trimmer. That’s an effective way to quickly deal with overgrowing chaparral and PO. Unlike most brush cuttings that we pick up and dispose of off the trail and out of sight, clippings that contain poison oak are carefully pulled to the side of the trail with a MacLeod (has a 4′ handle) and then shoved over the edge. We try not to touch any part of the handles of our tools to the PO leaves or stems.
The brush is all cut back, but there’s a lot of leaf litter to remove still.
The CORBA crew hiked about 1.4 miles to the end of the work area to tackle a corner where there have been mountain bike spills. It turns out that the brush had overgrown the inside of the turn so that the trail had become very narrow and people were riding beyond the outside edge where the dirt was soft. Mixed in with the overgrowing brush were some very vigorous PO bushes. Lacking the gas hedge trimmer, we chopped and hacked the brush around the PO, exposing as much of it as possible, then carefully chopped, hacked and lopped those branches. Where the brush had been removed was about a foot deep of leaf litter, including PO leaves, so we scraped all that away, revealing the original trail tread. Finally, we worked the dirt to give the tread a bit of an outslope (to shed water) and to make it even with the old trail.
That effort took the five of us about an hour and a half. After that, we worked our way back to the beginning, rebuilding blocked drains, filling a few very nasty but short ruts, and building new drains.
We’ve almost finished restoring this turn to its original condition.
Some of the drains we worked turned out to be old drains that were completely filled with dirt. Even thought the trail was on a steep cross-slope, the dirt had piled us several feet off the edge of the trail, like the Mississippi River delta. To make an effective drain, we had to cut down the brush that was growing up around these ‘deltas’ and then push a couple of cubic yards of dirt down the hill. That was before we could even start to construct our typical drainage nicks!
There was a major problem on the first half mile of trail beyond the top of the tunnel. Some person or group had dug poorly designed drains into the trail. They were too narrow and not sloped properly to drain water off the side. The biggest problem was that the outlet at the outside edge of the trail was narrow, so all the water was focused on one spot, eroding a deep rut. With just a few rainfalls, these ruts would start to encroach into the trail and would eventually destroy it. The Trails Council took care of these by widening them out, and also worked on some deeply rutted sections.
Overall we fixed up about a mile of trail, including brushing back the overgrowth. But be careful when riding this trail – the brush and poison oak is growing so quickly that it’s likely to continue to be a problem for some time.
Saturday, March 19, 2016, was a perfect day to do trailwork. There was moisture in the ground from the week’s rain, temperatures were cool, and the crew were able to ride to and from the work site via the Gabrielino trail. A half-dozen or so volunteers were already on their way to the work site when this group photo was taken.
Some crew members were already on their way to the work site
While several volunteers rode in via the Gabrielino, some opted to ride up to Brown Mountain and enjoy the fruits of their labor on the way down Ken Burton trail to the work site. It was the first time we had been able to ride all the way down to the 16th switchback without interruption. The volunteers who rode down Ken Burton trail were all in agreement that the efforts of the group over the previous five months had been well-worth the experience.
We were fortunate enough to have several SoCal High school league student-athletes and coaches join us for the day, along with members of the IMTBTrails.com mountain bike forum out of Santa Clarita.
This was a heavily damaged section
With the major brush work completed, the crew split into groups, concentrated on re-cutting the bench along a heavily damaged section of the trail, restoring outslope, and removing remaining roots and stubs from the tread.
Another crew worked diligently to rebuild the 16th switchback, using rock extracted from the tread to build an outside retaining wall on top of the old wire basket retaining structure that had failed. By day’s end, the switchback was completely rebuilt. We were fortunate to have the expert assistance of Hans from Bellfree Contractors on this major effort.
Rebuilding Switchback 16
By day’s end the crew had completed tread work almost all the way down to the 17th switchback, restoring one of the more heavily damaged sections of the trail so far.
So far, 81 individual volunteers have put in 1,408 total person-hours of work on this project in 14 scheduled work days, plus another 12 prep days. This is an impressive effort to restore this much-loved trail that was built by mountain bikers from the Mount Wilson Bicycling Association in the early 90s.
The next scheduled group work day on Ken Burton will be with Mount Wilson Bicycling Association on April 17, though there will be additional prep days before then. Contact Steve@corbamtb.com if you’re interested in helping prep before then (likely April 10).
Although we didn’t have to repair humongous El Nino rain damage that we were expecting, we still had ruts to fix that had been growing for years.
Filling in the big rut in the middle of the trail and re-establishing the gentle slope so water will run off the trail, rather than down it and making a rut.
About 40 people volunteered to help work on trails today for the annual COSCA Spring Trailwork Day. We split into two groups, about 15 working on the bottom of ‘Space Mountain‘ (the singletrack section of the Los Robles Trail West) while the rest went to the ‘Lily Tomlin Trail’ which connects the East and West halves of the Los Robles Trail. Both trails had major ruts, not having had any restoration work done on them for years. The work consisted of filling in ruts, restoring the trail outslope so water would run off it rather than down it, and building drainage nicks. On Space Mountain, we restored most of the first 1500′ of trail. Naturally, if we’d had more people and time, we could have done a lot more. The soil was perfect – moist and easy to dig and pack, and there was a low cloud cover to keep the temperatures cool.
Space Mountain is CORBA’s adopted trail and we’ve worked it a number of times in the past, but then we started at the top, or half way down, and worked our way to the bottom. This is the first time we’ve started at the bottom and had enough time to properly fix the ruts.
The group working on Space Mountain consisted of 6 from CORBA, 6 from the Santa Monica Mountains Trails Council (SMMTC) Meetup hiking group, and the rest from the Weekday Trailblazers Meetup hiking group. A few other Weekday Trailblazers were working on the Lily Tomlin Trail along with a number of SMMTC and other community volunteers.
After about 3 1/2 hours, we all headed back to the parking area where Rangers were preparing a barbecue lunch for the volunteers. Ranger burgers, hot dogs, chili and vegi-burgers always taste great! Chatting over our food, it was clear that everybody was happy with and proud of the work they’d accomplished to improve the trails for everyone. CORBA and the COSCA Rangers thank everyone for coming out to help and really appreciate their effort!
On Thursday, March 3, CORBA and MWBA Volunteer Sawyers and some additional dedicated volunteers continued work on the Ken Burton trail. This time they started at the bottom of the trail, from its junction with the Gabrielino National Recreation Trail, working up the lower switchbacks through a tangle of downed trees, poison oak, overgrowth, and near-impossible wayfinding. Using chainsaws was the only viable means of cutting through the several fallen oak trees that once shaded this beautiful old oak grove. This shaded oak grove was often a popular spot to re-group after challenging oneself to clean all the switchbacks, before attempting the most difficult between there and the Gabrielino trail.
Steve Messer had spent February 20 flagging out the original trail, using a combination of GPS tracks, searching for ground evidence of dirt compaction that may still be found even after six years, and a good memory of one of his favorite trail loops.
The group made what appeared an impossible task look relatively easy, working carefully to cut brush, downed trees, and have swampers carry away and stash the cuttings. It was most gratifying to follow the string of ribbons, and find the original tread under all that brush and debris. We made it to the 17th switchback, our target for the day.
Day 13, March 13, 2016
Erik from MWBA cuts through the brush
Ten days later, on Sunday, March 13, 2016, was our 13th group trailwork day. It was especially encouraging to see that all our previous work has held up perfectly to the recent rain and storms, with no rutting, and soil being packed down nicely. The first sections we worked on last November are maturing nicely.
Our 13th worday on Sunday March 13, was a milestone day. With 21 volunteers out putting in a 7 hours or more, we were able to do a first-pass brushing on the last remaining section of trail, linking to our March 3rd work and to the bottom of the trail. This was a great milestone in this restoration project, now in its sixth month. We had cut brush from the entire trail corridor.
While the brushing tools and swampers diligently plugged away to reopen the trail corridor, the tread crew made quick work of the tread on about .3 miles of trail. With the damp dirt, cool temperatures, and sense of determination among the volunteers–many of whom have worked multiple days on this project–we had an extremely productive day.
Ryan and Stephanie work on tread restoration
There is still work to do on the 16th switchback, but it was rendered temporarily passable for the day. The last half mile of the trail is far from finished, needing a second pass with the hedge trimmers and extensive treadwork. But with some careful hike a bike the group was able to ride out the bottom of the trail, completing the loop with the closed Gabrielino trail. It was a truly gratifying day for all who made it.
We currently estimate two to three more days working on the bottom of Ken Burton trail, and an additional day on the Gabrielino trail between Oakwilde/Ken Burton and Paul Little.
We were also joined by an Ultra Distance runner, and past AC100 runner. Many trail runners are just as excited to get this trail opened as mountain bikers. During our last two days of work and long before we were finished brushing the corridor, we had hikers come up from the bottom, bushwhacking their way through until they heard us, then asking where the trail was. After reminding them the trail was closed to the public and we were working as Forest Service volunteers to rebuild it, he headed on beyond our work area for a leisurely stroll up the newly groomed segment of the trail, and all the way to Brown Mountain. People put far too much faith in outdated maps and information.
After loading up tools, the group rode out via the Gabrielino trail back to the trailhead and our meeting spot. This section of the Gabrielino trail was worked on two years ago by Bellfree Contractors. volunteers, and the Los Angeles Conservation Corps with the financial support in the form of an REI grant to CORBA, and funding from the Forest Service for the project. While the section was rebuilt, it has been two years and it also once again needs some minor work. Between Oakwilde and Bear Canyon the trail is in poor condition and almost entirely gone and unrecognizable for a long stretch. Plans are underway to continue work on rebuilding that section of the Gabrielino, once again in partnership with the LACC, USFS, Bellfree Contractors and REI.
Both the Gabrielino between Paul Little and Bear Canyon junction, and the Ken Burton trail, remain closed to the public by order of the Forest Service. Please respect the closure until the Forest Service opens the trails. We’re just as eager as everyone else to finish the project and be able to ride, but there are many steps to go through before that can happen, and it is the decision of the Forest Service as to when and if the trail will be opened.
For all the volunteers who have joined us for at least two days, we’ve ordered a special commemorative T-shirts. It’s our–CORBA and MWBA– way of saying thank you. If you haven’t put in two days, there are a few more coming up starting this weekend and in April.
On Saturday, February 27, 2016, fifteen dedicated CORBA volunteers came out to support the City of Rancho Palos Verdes efforts to restore the Toyon Trail. Organized by long-time CORBA PV coordinator Troy Braswell, the group took part in trail repairs, invasive weed removal, and planting native shrubs. They worked alongside City employees and other volunteers. Cory Linder, from the City’s Parks & Recreation department was on hand to oversee and coordinate all the volunteer efforts.
The City of RPV has been conducting ongoing restoration work every Saturday in February, with the final work day scheduled for this coming weekend, March 5th. To learn more about volunteer opportunities in Rancho Palos Verdes, visit http://www.rpvca.gov, and stay on top of RPV happenings at CORBA Palos Verdes.
We are happy to see the RPV Parks & Rec department stepping up their volunteer program, and are even happier to be able to contribute. Thanks to all the dedicated volunteers who came out to improve the trails and landscape for everyone!

Ten CORBA and 17 other volunteers helped to restore 3/4 miles of the Backbone Trail (Yerba Buena segment) this past Saturday February 27.
The outside berm of the trail is pulled back to fill in the rut, and to give it a slight slope so water will run off it, rather than down it. This is called ‘outsloping’ the trail.
This trail was built about 12 years ago and has had very little, if any maintenance work done on it since. Overall it has held up very well, which shows how well it was designed and constructed, but the lack of rainfall over the past several years has certainly contributed to its longevity.
Nevertheless, most of the original drainages were completely filled with silt and had become ineffective, allowing water to run down the middle of the trail, developing and enlarging ruts. As such, most of our work was spent fixing ruts, and repairing drainages or building new ones, to keep ruts from re-forming or enlarging. One long-time volunteer used a gas-powered hedge trimmer to cut back the brush that was starting to impinge on the trail while two people followed along behind to dispose of the cuttings.
A finished drainage nick.
This CORBA crew embarked on a task that was new to us by completely rebuilding a section of the trail about 100′ long. The berm on the outside of the trail that keeps the water on it was chopped up. The dirt was then dragged back over the trail, filling in the center rut and used to re-establish the normal outslope that allows water to flow straight across and off the outside edge of the trail, rather then down the middle to make a rut. This took about three hours. For the rest of the day we joined in the other volunteers in clearing and building drainages.
We packed up about 2 pm, a littler earlier than usual, then some CORBA volunteers drove into Thousand Oaks for thank-you lunch on CORBA at the Stonefire Grill.
Thanks to all the CORBA and other volunteers who came out to help restore this trail! There are many more photos in our Feb 27th photo gallery for you to view.
Come out and join the Conejo Open Space Conservation Agency (COSCA), CORBA, the Santa Monica Trails Council and other volunteers for the Annual COSCA Spring Trailwork Day. We will be working to restore part of Space Mountain (Los Robles West) and other nearby multiuse trails.
At noon, following the morning of trail-building, workers will be treated to hamburgers / vegi-burgers, chips, fruit and drinks while enjoying the camaraderie of fellow trail enthusiasts!
Wear protective clothing (long-legged pants, long-sleeved shirts, sunglasses), sturdy shoes, gloves, hat and sunscreen.
No experience is necessary and you work at a pace that is comfortable for you. Tools and instructions on how to use them safely and effectively will be provided. Must be 18+ years of age or accompanied by a parent or other responsible adult. Beware of poison oak, ticks & rattlesnakes.
Follow directions of park rangers and trail crew leaders at all times.
Pre-registration is required so that COSCA will have enough tools, crew leaders and food!
