“Lost Man” is a documentary by R.S. Prosch about the trip and the search for Clyde. The video starts in 1940 with Clyde and his wife, Flo, traveling around Colorado and then after Clyde’s disappearance details the search efforts. Because the video was made in 1941 and has transitioned through multiple video technologies and was stored for a long period on VHS tape, the quality is poor.
