On Thursday, in preparation for the annual Santa Monica Mountains Trail Days held every year in Pt Mugu State Park, I drove my now very dusty car down the main Sycamore Canyon trail and parked at the bottom of the Wood Canyon Vista Trail, a segment of the Backbone Trail. I hiked up the trail and flagged 59 spots where drains were needed – mostly to clean out existing drains that had become clogged with silt from the winter rains, but also some new drains about 2/3 of the way up the trail.
Saturday, CORBA volunteers and few others install drains and repair ruts on the Wood Canyon Vista Trail, a segment of the backbone trail.
Saturday morning, the State and National park services drove 17 of us, including 2 youngsters, and our work tools to the bottom of the trail. After grabbing our tools, we hiked 1.5 miles up to the work area, about 2/3 of the way to the top, and proceeded to work down. Altogether, we put installed or cleaned 26 drains.
The area of greatest concern was at the start of our work area where the trail passes through a grassy area and is solid clay. Most of the rest of the trail is very rocky. This clay section is pliable, quickly becomes depressed in the middle where a rut erodes when it rains. This section of the trail was completely restored during trailwork in February 2015, yet it was as rutted as ever after just two years. A narrow but deep rut had developed in the middle of the trail, just wide enough for a mountain bike tire to slip in and get jammed.
We learned that leveling the trail doesn’t last here, so instead we cut a drain in about every 50 feet. That involved cutting through the berm (the dirt that builds up on the outside edge of the trail and keeps the water from running off), the first few inches was as hard as concrete, despite having been rain-soaked a few weeks earlier. The drains were 3 to 5 feet wide. We used the dirt we dug out of the drains to fill in the rut on the trail. Now we have a section with frequent drains to keep the water from running all the way down the trail, and the rut is filled with dirt. Hopefully this restoration will last longer than two years!
Overall, we dug out 26 drains over 2100′ of trail and filled in about 500′ of rut! Well done, everyone!
Saturday restoration on the Upper Sycamore Trail.
While the CORBA crew was working on the Wood Canyon Vista Trail, the other volunteers (about 60 of them) worked to restore the Upper Sycamore Trail where Sycamore Creek crosses it a number of times. By all accounts, this trail was decimated by the stream. This is a very shaded trail in a deep canyon and popular with hikers, but it’s in the Wilderness Area and so closed to mountain biking.
Everyone was back to the staging area by about 2:30 so we spent the afternoon relaxing and chatting with friends until the barbecue dinner. As usual, we had chicken, hot dogs, veggie burgers, baked beans (regular and veggie), salad and garlic toast. It was up to us to bring our own beverages. As dinner was winding down, the prize give-away started. There were so many prizes that everyone must have gotten one.

The work continued on Sunday morning with a much smaller force of about 30 total. We all shuttled up to Upper Sycamore Trail, then split into two crews. One hiked up to the top of the trail to work on tread issues while the other worked on clearing overgrowing brush from the bottom. Sunday is always a smaller and shorter event; we were back to the staging area by noon to enjoy left-overs from Saturday’s barbecue.
CORBA would like to thank all the volunteers who came out to help fix up our trails in Pt Mugu State Park. Everyone did a great job! And a special thanks goes to the Santa Monica Mountains Trails Council that organizes this event every year.
You can see all the photos from this weekend in CORBA’s photo gallery, or photos from Steve Messer and Xander Tenai . Take a look to see what we accomplished.
This annual Conejo Valley event always helps to put some very sweet trails into good shape. Be sure to stay afterwards for the free lunch and raffle.
