About 120 volunteers arrived at 7:30 Saturday morning, October 19, to help build a new trail in the Western Plateau area of Thousand Oaks for the 23rd Annual COSCA Trailwork Day. Eleven of these volunteers had registered through CORBA. The Santa Monica Mountains Trails Council made a huge contribution as most of Saturday’s 12 crew leaders were members of their Trail Crew. Other crew leaders were from CORBA or were COSCA rangers.
The new trail starts 2 miles from the new Hill Canyon bridge near Santa Rosa County Park. Volunteers hiked in, or caught a ride with the 4×4 vehicles that drove the tools to the new trailhead. After picking up their tools and learning about safety during trailwork, the dozen teams of about 10 headed up to their designated work areas.Most of the new trail is on soft, crumbly dirt on a hillside with a gentle cross-slope. The grass and chaparral had already been cut away, so most of the work involved scraping the dirt to remove the last stubbles of grass and making a 5% outslope so water would run across and off it, rather than down the middle, cutting a rut.
However, there some switchbacks and rocks that were in the way, so some crews had rock bars to help them along.
The new trail, yet to be named, climbs the east end of the southern ridge above the Western Plateau. In many places it is quite close to the edge and so provides amazing views of both Hill Canyon and the rest of the Western Plateau.Everybody headed back about 11:15 to get to the thank-you lunch, barbecued by COSCA rangers, and the prize giveaway. As always, the rangers did a superb job with lunch. About a dozen people won prizes, including the grand prize of a new Giant mountain bike.
