Class B First-hand BFRO #140

Characteristic vocalization heard by hunter on Hayden Mountain

8 August 1996 Morning, about 8:30 am Ouray, Ouray County, Colorado 2 witnesses

Account

The witness and a companion were archery hunting in high-elevation basins in western Colorado when they heard a single, extremely loud scream lasting several seconds from the direction of their camp. They initially attributed the sound to a mountain lion, but acquaintances who hunt mountain lions did not recognize the described sound. Years later, after hearing a purported Bigfoot vocalization on television, the witness reconsidered the 1996 incident as possibly Bigfoot-related.
