The road on the bluffs, was that on stage or small scale model or was that a real location in California too?
The fishermans body location is incorrect. The proper location is further south at Albion Cove. The bridge supports in the background are clearly of the Albion River Bridge. A photo of the bridge is here at this site. http://www.bridgeofweek.com/2016/04/mendocino-county-california-bridges.html
Jon, thank you for pointing that out. Other than it's proximity to Mendocino, I always assumed it was the Big River Bridge and it had just been rebuilt at some point since the film came out in 1981 but I was incorrect.
