A white, Bigfoot-like creature was seen on one 1973 night in Pennsylvania. It appeared to be carrying some kind of glowing orb, and was associated with the appearance of a silvery UFO. There is a long and highly unusual history of Bigfoot-like entities emerging from UFOs in the surrounding area.
The Incident[]
The humanoid was covered in white fur, and had glowing red eyes. It appeared to be holding a glowing large, luminous sphere in its hands, and was 8ft tall. This is the bizarre sight to which two girls in Beaver County, Pennsylvania, bore witness at 21:30pm on the 27th of September 1973. After seeing the frightening figure, the girls bolted back into the house and their father went out into the woods in an attempt to track down the creature. He was gone for over an hour, and when he returned he refused to talk about what he had seen.
At the same time as he was in the woods, several nearby people claimed to see a silvery object hovering over the forest, and at one point it apparently emitted a beam down into the woods. This unique, but sadly short report was submitted by Stan Gordon in the Mufon UFO Symposium of 1974.
