This was a scheduled trail maintenance project. This section of the Backbone Trail was heavily impacted by the Woolsey fire a few weeks ago. This was the fourth in a series of work days to assist NPS with remediation efforts on this section of the trail. The objective today was to complete this project. There were 16 volunteers present. Met at the Sandstone Peak parking lot. Began work. Hiked up the trail to point where we left of off on the last trip (approximately 0.5 mile). The NPS leader had previously flagged the locations where she wanted drains cleaned or installed. We began working our way downhill working at all the flagged areas. In addition, we cleaned some drains which were not flagged. We also installed three new drains which were not flagged, but were needed. We all, we cleaned/installed 14 drains. This will prevent future damage to three existing washouts on the trail. Stopped work and hiked back to the trail head. Arrived at the parking lot, just as the rain began. Not only completed today’s event, but completed the overall project. This trail is in terrible condition. The tread has been neglected for several years and there is much erosion in need off attention. While our work was significant, at best, it only slows the derogation of the trail. The trail needs major attention (with heavy equipment) to restore it to NPS trail standards. Total volunteer hours: 16 Volunteers x 6 hours = 96 hours Feet of trail serviced: 2, 600
