Fairfield (p. 171) writes:
"At the Black Rock range they camped one evening beside a small stream ever since known as Clapper creek. The camp was in a nook of the canyon overlooked by high bluffs on three sides There was a little feed for the horses and the place was a very pleasant if in those times dangerous location for a camp."
