The Patterson–Gimlin film is an American short motion picture of an unidentified subject. The footage was shot in 1967 in Northern California, and has since been subjected to many attempts to authenticate or debunk it.
The footage was filmed alongside Bluff Creek, a tributary of the Klamath River, about 25 logging-road miles northwest of Orleans, California, in Humboldt County. The film site is roughly 38 miles south of Oregon and 18 miles east of the Pacific Ocean. For decades, the exact location of the site was lost, primarily because of re-growth of foliage in the streambed after the flood of 1964. It was rediscovered in 2011.
