This was a joint effort with CORBA members. The event was well-attended and we made good progress. We had 12 occasional volunteers (incl. CORBA) and 10 regulars for a total of 22. Jason Finlay joined us to support the shuttles. We met at the Wendy and Potrero, consolidated into 5 vehicles and shuttled down to the trailhead. After a tool talk and a safety talk, the volunteers were distributed over 4 crews, one crew built a substantial retaining wall and restored a 50 or 60 foot segment at the bottom of the trail. The next three crews focused on clearing slough and reshaping the trail, brushing, lopping, and installing or restoring a total of 12 drains, and, finally, the last crew focused on removing a very large boulder that juts out onto the trail and is preventing CSP from sending the Sweco up the trail to fix several spots above our work area. Jason went off to chainsaw a tree across the Upper Sycamore Canyon trail. Everybody headed back to the trailhead, and after refreshments, we got back in the vehicles for a short shuttle to the bottom of the U. Sycamore Canyon trail, to move off the trail the pieces of the tree that Jason cut up. Total volunteer hours: 22 x 6 = 132 + (3 x 3) - John, Anne and Steve scouted the trail on Friday. 141 hours for this project Feet maintained: 2,350
