Work consisted entirely of clearing and installing new water drains (some 13 total). This work is considered vital to help prevent further erosion of the trail after the Woolsey fire when more winter rains come. We expect lots of silt and debris from rains to create further damage in the near future. Work will continue here as time permits. Two of our crew hiked down the Chamberlain trail on the Backbone to assess trail conditions. They will submit a separate report but reported that the trail is mostly clear but will be subject to severe erosion and debris slides when more rain comes. The entire trail corridor from the Sandstone Peak parking down to the trail juncture of Chamberlain and Old Boney was burned. Feet worked: 1000 Crew size: 8 Hours worked: 6 Total hours: 48
