Of all the documented sasquatch attacks, the Ape Canyon incident of 1924 was one of the most notable and frightening in history.
In mid-July of 1924, Fred Beck and four other men were gold prospecting in what is now called Ape Canyon (in the Lewis River area near Mount St. Helen's).
They began to notice evidence of "visitors" around their cabin: large human-like footprints and strange noises in the area at night. They also heard noises that sounded like chest-thumping, along with strange high-pitched whistling sounds from ridges around them.
