Mt. Cameron Yeti Alien
The Mt. Cameron Yeti Alien was sighted in June 1932 at Mt. Cameron, in Colorado. It was sighted by a man named William Lamb. He found tracks measuring 17 inches long and 4-6 inches wide. He saw a fireball dropping from the sky which vanished and transformed into a creature. It stood 8 feet tall and resembled the yeti. The creature started chasing him, and he eventually managed to escape by jumping off a cliff onto a pine tree. He believes this is the same creature as the yeti from the Himalayas.
