This 1955 photo is likely taken off the shoulder of a road from which side cast materials form the slope of the inner gorge over Signal Creek. Side cast material can increase the burden on a hillslope below a road causing failure of the slope and major contribution of sediment to streams. Photos originally from California Department of Fish and Game but copied form the archives of the E-Center Mendocino Fisheries Program in Ukiah.

This photo shows a logging road built on top of an emphemeral stream course in the Signal Creek sub-basin. Note the rills and gullies forming on the road, which has a high risk of stream capture, where the stream might actually jump onto the road and wash away massive amounts of fill. Photo taken by the California Department of Fish and Game in 1955.
