Go back to the Bigfoot Compendium.
The claim has been made that purported Sasquatch foot casts contain textures that represent healed scars. One of the most notable is that of “Wrinkle Foot”, a set of right and left foot casts brought forth by Paul Freeman.
Unfortunately, A formal paper detailing the analysis of the surface detail of “Wrinkle Foot” has not been forthcoming at this point. A short account did appear in the November 2000 issue of Fate magazine:
The “scar” texture of “Wrinkle Foot” is not detailed at length in Jeff Meldrum’s Sasquatch book. From page 255:
What most impressed Officer Chilcutt were multiple examples of healed scars that appeared on a particular pair of casts from the Blue Mountains in southeastern Washington, where the soil has a high content of loess. Dr. Krantz had previously referred to these casts as “Wrinkle Foot” due to the extensive indications of coarse dermatoglyphics. The deep, clear footprints were found in wet mud and preserve much detail of the skin surface. Chilcutt reasoned, “If this animal is walking through the wilderness, he’s bound to come across rock and rough terrain that will cut the bottom of his foot. As the wound heals, the ridges curl inward toward the scar.”
A photograph at the top of page 257 is captioned “Close-up of ridge detail showing healed scar”. Unfortunately we are not told explicitly if this is “Wrinkle Foot”, but it appears to be. No metric is included in the image in Meldrum’s book.
Here is a photograph of the texture in question. Remember, this is a multiple generation cast copy, and so is not as sharp as the original. Nevertheless, even with this copy we can see the main line of the “scar” with small lines branching off the sides. I have intentionally included my own fingers in the photograph to illustrate how much larger this texture is than human dermal ridges. The size of the feature alone is grounds for reasonable skepticism that this represents real primate dermal ridges.
Recently, a surprising image was forwarded to me from a friend of mine in Arizona, Brenden Bannon. Brenden cast a track he made using a fake rubber foot to impress mud in his back yard. The result is striking, as a surface texture similar to the “scar” of “Wrinkle Foot” spontainously appeared running across the “ball” of the foot:
Here is a close-up of the texture in question:
Upon close examination, small lines can be seen that connect to, but radiate away from, the main fissure.
While Bannon’s cast is a preliminary finding, it would seem to cast doubt on the notion that the texture seen on “Wrinkle Foot” is strong evidence of Bigfoot’s dermal ridges. It may be the texture is related to a suction effect, or to a cement-substrate interaction, or both.
