Pike County Gulch
Pike County Gulch is a coastal valley in Marin County, California, United States, which is associated with a small stream. It is located between Wilkins Gulch and Audubon Canyon.
The stream descends the western slope of the Bolinas Ridge, crosses State Route 1 about north of Stinson Beach, California, and drains into the northern tip of Bolinas Lagoon.
The gulch contains an ore vein thick containing pyrite, located a mile south of the Union Gulch Mine.
