The large wash north of U.S. Highway 62 just 2 miles east of Vidal Junction is an excellent site for collecting chalcedony, which can be found from Highway 95 extending east approximately 1 mile. The best method of working a site is to park safely off the pavement and walk east through the wash. The bright white chalcedony is easy to spot against the darker soil.
From Needles, CA, take U.S. Highway 95 south approx. 35 miles to BLM Route NS660-Pyramid Peak Road. Turn left on NS660 and drive approx. 2 miles. The rock collecting area will be on both sides of the route.
