The Cripple Foot Tracks or Bossburg Tracks are a series of 1,089
tracks found in Bossburg, WA in 1969. These tracks are human-like in
appearance, but much larger and are believed to be left behind by
Bigfoot. These tracks are unique in that the right foot appears to have a
deformity. The creature is speculated to have a condition similar to
"club-foot" found in humans, or "skew-foot" determined by Jeff Meldrum.
The tracks were found by Rene Dahinden, Ivan Marx, and John Willison
Green. The tracks are convincing to many experts as they seem so
unlikely that they could be hoaxed,
based on the nature of the tracks. They have been called into question
though because of their association with Ivan Marx and his allegations
of being a hoaxer. In 1970, Marx claimed to have caught the Cripple Foot
creature on film.
