On Saturday, November 8th, 13 CORBA volunteers and 6-8 from the Santa Monica Trails Council combined forces to fix up the 2.5-mile long singletrack section of the Backbone Trail between Mulholland Hwy and Etz Meloy Motorway. The gentle grade of this trail, combined with sweeping turns, easy switchbacks, great views and connections to the rest of the Backbone Trail make this a favorite for mountain bikers.

Being more used to working a distance from the trailhead, the Trails Council crew hiked to the top and worked their way down while the CORBA crew started near the bottom and worked up the trail. We skipped the first few hundred feet because of the presence of invasive weeds; we didn’t want to spread the seeds around by disturbing these aggressive plants. Both groups completed about a half-mile of trail.

We focused on removing brush at the side of the trail, but a few workers concentrated on removing silt and other debris from the drains. Our priority is generally to make sure the trails are well drained so rainwater doesn’t erode ruts down the middle. The drains on this trail were plentiful and well designed when the trail was built about seven years ago, so we didn’t need to build any new ones as we do on most trails.

COSCA Annual Trailwork Day attracts 150 volunteers; 0.6 miles of trail built/repaired

Monday, October 20th, 2014

This past Saturday, October 18, almost 150 volunteers turned out to help rebuild the Conejo Crest Trail and a connector between this trail and the White Horse Canyon Trail in Thousand Oaks. This included 20 CORBA volunteers and several riders from nearby high school mountain biking teams. The work was divided into 5 distinct projects.

Chopping out a stump on the new trail to bypass the Descent of Death

Chopping out a stump on the new trail to bypass the Descent of Death

The most important was to build a reroute around the Descent of Death (watch the video of mountain bikers on the Descent of Death). This new trail is just over 1000′ long, compared to 680′ for the Descent itself, so it is about 1/3 less steep. Three crews were assigned to this challenging section with lots of big rocks, some very steep cross slopes, and many sturdy stumps to remove. The amount of work needed was more than could be accomplished by the available volunteers in just 3 working hours, so COSCA will complete this section later. However, the most difficult parts were completed so the bypass trail is open for use.

The connector to White Horse Canyon Trail is very rocky because rainwater has washed away all the soil. We removed the biggest and loosest of these rocks.

At the bottom of the bypass trail is a connector trail to the White Horse Canyon Trail. This 835′ long connector goes straight down the hill with no diversions to get the water off it. As a result, rainwater has run straight down it for years and it has become very rutted, and rocky where the soil, sand and smallest rocks have been washed away. In addition, it was somewhat overgrown. Three crews were assigned to this section to clear the brush, remove the worst of the loose rocks and build drainages to get the water off and minimize future runoff erosion. These crews finished early and went on to help build the bypass trail. Another crew was working to remove loose rocks from the Conejo Crest Trail for about 1100′ from the top of the Descent of Death. The bypass trail crossed an illegally built trail that ran from the top of the Descent of Death almost straight down the hill to the Los Robles East Trail (Edison Road). A ranger-led crew worked to rehabilitate the ground around this trail, to restore as much as possible the natural contour of the land. Berms and jumps were knocked down and raked over. The trail was blocked to prevent future use and further erosion and degradation of the public open space. Finally, a group of youngsters worked to beautify the trailhead to the Triunfo Trail at Triunfo Community Park by raking out the trail, building a pretty border out of rocks, and planting native plants in the bare area next to the trail.

After the work period, the volunteers gathered at Triunfo Park to enjoy a barbecue lunch prepared by the COSCA Rangers. About a dozen people won prizes in the give-away to thank the workers, including one lucky volunteer who won a Giant mountain bike. You can see more photos of the work in our gallery of trailwork photos. The trail crew leaders were COSCA rangers and volunteers from CORBA and the Santa Monica Mountains Trails Council. These folks and the organizations they represent would like to give a hearty thanks and shout-out to all the volunteers who help keep the trails in great shape for all trail users!

President’s Message: The Station Fire

Thursday, June 5th, 2014

20110401-Station_Fire_sign_burning_3It has been almost five years since the Station Fire was set by arsonists along Highway 2 near the base of Mount Lukens. I was there on August 26, 2009 when it started. I was also there last week when the Station Fire General Closure Order expired. This opened up Strawberry Peak loop, a trail system that has been the focus of several different groups for the past eighteen months. Though it’s a significant milestone, there is much more to be done.

Mountain Bike Magazine Station Fire

Mountain Bike Magazine Station Fire

This takes me back to a June 2010 Mountain Bike Magazine article about the Station Fire. While the magazine is no longer published, a copy of the story is archived on our web site. Reading it will help you realize what has been accomplished since.

We all wish that things could have happened faster, but the assumptions of the article have held up. Matt Lay/Mount Wilson Bicycling Association (MWBA), and I were featured in the article as mountain bikers on a mission to help restore the trails. Both CORBA and the MWBA have lived up to that promise, with many trails affected by the fire now open due (at least in part) to our efforts. We have to thank our volunteers, our members, and REI for their generous support, all of whom helped make it possible.

Of course, mountain bikers were not alone in the effort to restore trails. Many nonprofit groups, trail user groups, and individual volunteers continue to make significant contributions to restoration and maintenance. Professional crews including Bellfree Contractors and the LA Conservation Corps have also been involved.

As mentioned,  the work is not yet done. The general closure expired and was replaced by a much more manageable list of closed trails. Among them are several fire roads and at least two local mountain biking favorites: a section of the Gabrielino Trail and the Ken Burton Trail. CORBA and the MWBA have pending work plans for both trails, and the Forest Service is working to reopen the fire roads. Stay tuned.

And there will always be a need to do trail maintenance, above and beyond restoration efforts.

Trails don’t maintain themselves. Join us.

2014 Santa Monica Mountains Trail Days Trailwork Report and Photo Galleries

Monday, April 28th, 2014
Rangers serve the barbecue on Saturday night. As well as hot dogs, there was chicken, tri-tip beef and veggie-burgers.

Rangers serve the barbecue on Saturday night. As well as hot dogs, there was chicken, tri-tip beef and veggie-burgers.

This past weekend, a large number of volunteers from CORBA, the Santa Monica Mountains Trails Council, the Sierra Club and other organizations, and individuals gathered for the 33rd annual Santa Monica Mountains Trail Days at the Danielson campground in Pt Mugu State Park. Folks could arrive Friday evening, camp overnight, help with the trails on Saturday, enjoy the barbecue dinner prepared by park staff, win some cool swag in the prize give-away during dinner, camp overnight, help with the trails on Sunday, have lunch back at the campground, then depart for home. Of course only a few people stayed for the whole weekend, but many camped for at least one night, and most stayed for the Saturday BBQ and prize give-away.

On Saturday, there were about 110 volunteers who split into five groups. The largest groups worked on Old Boney Trail in the State Wilderness Area and Sage Trail. Others went to the top of Hidden Pond Trail and youngsters under 10 cleared small rockfalls off the Sin Nombre and Two Foxes Trails. A dozen hardy souls (with hardy soles) hiked almost three miles (and up about 1400′) carrying tools to work on the Chamberlain Trail, also in the wilderness area.

The group of about 30 volunteers who worked on Sage consisted of CORBA folks, a few geocachers, and others. The trail had just been SWECO’d (plowed by a small trail-sized bulldozer) to level the trail, smooth out the ruts, and narrow it. The trail is narrower now because it used to be the full width of a fire road, and now the travel surface is about half as wide. The SWECO is only able to get so close to the edge, so the work consisted of pulling down the berm (pile of dirt) the machine left at the outside edge of the trail, sloping the trail about 5-degrees to the outside so rainwater will run off, rather than down the middle, and removing the larger rocks.

Putting the finishing touches on the Sage Trail on Saturday after it was leveled, smoothed and narrowed by the SWECO trail bulldozer.

There were also a few spots of severe erosion and rutting on the side of the trail where rain water had run off, taking some of the trail with it. In one case, the erosion extended about half-way into the trail. To prevent future rain from extending these ruts and eventually washing the trail away completely, we built rock walls down the ruts to reinforce the side next to the trail. The idea is that the water will run off the trail and down the rock wall, protecting the dirt underneath from being washed away. The rocks will also slow and disperse the water, so it doesn’t wash away the dirt below the wall and undermine it.

Overall we worked about 2300 feet of trail, from the bottom to where the now-closed Art’s Trail joins it.

We headed back to the campground at about 2:00 pm, although crew leader Virginia from the Trails Council stayed about a half hour longer, and CORBA’s Steve Messer stayed even longer. Some people just won’t quit until the job is finished!

We always have a much smaller group for the Sunday work day, so all 30 of us returned to Sage Trail to finish off the top 1700′. It only took until about noon to get this shorter section completed.

Sage Trail is a little loose after our trailwork, but it’s not too loose to ride. It should be packed down in two or three weeks, as Guadalasca Trail was after we did the same work there last spring. The trail will also regain its single-track width after enough people have ridden it to define a preferred course.

CORBA, the Trails Council, local chapters of the Sierra Club, California State Park, the National Park Service and other would like to give a tremendous Thank-You to all the volunteers who helped over the weekend, both working on the trails to keep them in top shape, and organizing and coordinating in the camping and registration area!

Niner Bike Frame is Grand Prize for Trailwork Volunteers

Friday, March 28th, 2014
Could it be YOU who wins a frame like this Niner?

Could it be YOU who wins a frame like this Niner?

As part of the thank-you for volunteers who help with maintaining our trails in good riding order, CORBA has been giving away mountain biking swag at the end of each event. To speed things up on trailwork days, and to allow some really great  (ie, expensive!) prizes to be given away, we will instead have a drawing at the end of the year for all the volunteers who come out during that year.

We have a Niner frame waiting for some lucky volunteer, plus other great prizes including grips and saddles from Ergon!

In order to be eligible for the drawing, volunteers must register for events in advance on our Meetup group, show up at the event and sign the standard waiver form. At the end of the year, we’ll go back through all the Meetup events and count the number of times each volunteer helped out. Everyone will get one chance in the drawing for each time they participated.

Now by helping to keep our trails in good shape, you will have the satisfaction of knowing that you’re giving back to the trails community, of contributing to the enjoyment that others have in our open spaces, and also having a chance at scoring a sweet ride from CORBA and Niner!

Good luck and thanks for helping out!

COSCA Spring Trailwork Report, Photos and Video from March 22

Wednesday, March 26th, 2014

As well as this section, there are lots of people working up above!This past Saturday, March 22, roughly 60 volunteers converged on Wildflower Park for a short hike to the work area at the bottom of the new trail. By noon, the volunteers had built the 0.25-mile long Castillo Trail that now connects Wildwood Trail in the canyon to Castillo Circle on the mesa above.

The Conejo Open Space Conservation Agency (COSCA) rangers had previously removed the chaparral and marked the route of the trail with little orange flags. It was up to the workers to dig out the dirt to make an even trail tread. The trail crossed a steep hillside, so there was a lot of dirt to be moved along much of it’s length. The route included two nearly 180-degree turns, necessitating a switchback and a climbing turn. Each of these features took 6-8 people all morning to complete.

After the work was finished, the crew returned to Wildflower Park to enjoy a barbecue lunch prepared for the volunteers.

Steve Messer, CORBA’s president, brought along his GoPro and made a time-lapse video of the trail building, and of the first ride down on his new hard-tail 29er. You can see the video on YouTube or Vimeo.

You can also view the photo gallery of the trailwork.

February 23rd Space Mountain Trailwork Report and Photos

Monday, February 24th, 2014

This past Sunday, 12 CORBA volunteers and two COSCA rangers headed up the “Space Mountain” section of the Los Robles Trail in Thousand Oaks to fix up the 1.7-miles long switchbacks part of this singletrack trail before the winter rains worsen the ruts.

Clearing slough from the trail

Clearing slough from the trail

By all standards, the work was a tremendous success! We cleared slough from 230 yards of trail, installed about a dozen new drainage nicks, cleaned debris out of about a dozen existing drainages, and whacked out about 20 stumps.

From the top of the switchbacks, we continued another a short distance to fix the falling slough on 230 yards of trail. Slough is rocks, dirt and other debris that falls on the trail from above. So much had fallen that half to 2/3 of the trail was covered, forcing people to the very outside of the trail. We could see many tracks where people had ridden off the edge and possibly taken a tumble. With the trail now returned to it’s full width, that hazard is much reduced.

Next, we headed back down to the bottom, installing new drainage nicks as we went, and hacking out stumps that had become hazards in or near the edge of the trail. Finally, as we got to the lower half where we had installed drainages in previous years, we cleaned out those that were becoming clogged with silt so they would continue to be effective in diverting rainwater off the trail.

You can see the volunteers working in the photo gallery of Sunday’s trailwork day.

After the traditional prize give-away to thank the volunteers, CORBA treated everyone to lunch at Baja Fresh.

Thanks to all the volunteers who came out to help, and the COSCA Staff who joined in to support us!
