Class B First-hand BFRO #20306

Young man claims possible sighting at night near Lake Mary, outside Mammoth

July 2005 night, pitch black Mammoth, Mono County, California 1 witness

Account

The witness was staying at a cabin near Lake Mary and took two dogs for a night walk. The dogs began growling and pulling toward sounds of rustling leaves and breaking branches. The witness shone a flashlight and saw a huge ape-like but human-built figure about 200 feet away watching and swaying between trees. After a minute or two the figure turned and walked away, and the witness hurried back to the cabin.
