Gravelly Valley Airstrip (1Q5) lies on the shore of Lake Pillsbury and attracts recreationists who enjoy fishing, seasonal canoeing, boating, jet skiing and hiking.
According to the Spring 2004 Pilot Getaways article by Greg Illes, the airstrip was built in the 1920s by W.P. Fuller of Fuller Paint, then became a base camp for firefighting in Mendocino National Forest. Some of the first U.S. aerial firefighting missions originated here.
