Pike County Gulch is a coastal valley in Marin County, California, United States,[1] which is associated with a small stream.
It is located between Wilkins Gulch (to the northwest) and Audubon Canyon (to the southeast).
The stream descends the western slope of the Bolinas Ridge, crosses State Route 1 about 3 miles (5 km) north of Stinson Beach, California, and drains into the northern tip of Bolinas Lagoon.
[2] The gulch contains an ore vein 4 feet (1.22 m) thick containing pyrite, located a mile (1.6 km) south of the Union Gulch Mine.
