Daytime sighting by six siesmographic workers in the Uinta Mountains

January 1984 about 12:15 p.m. Evanston, Uinta County, Wyoming 6 witnesses

Account

Six coworkers on a seismic crew were eating lunch on a hill when they noticed a dark hair-covered figure moving through timber about 500 yards away. The figure walked upright on two legs with long swinging arms and made muttering sounds before noticing the men, then fled into the timber breaking branches. The men then heard loud screaming and moaning vocalizations from the timber and left the area by helicopter.
