The Patterson–Gimlin film was shot in 1967 in Northern California.
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
