Track number 57 in the London series shows four digits. The first three digits are deeply impressed with nice striations showing either the grabbing action of the toes, or the pull out as the creature lifted its foot upwards out of the substrate. The fifth digit, though possibly seen in the photograph taken of the print before it was cast, didn’t seem to show up in the cast itself. The first digit impressed quite deeply, pushing into the substrate 1.9 cm.
The heel is nicely rounded and very natural looking. Its lateral edge is deeply impressed with a rounded side wall suggesting a living, maleable foot rather than a wooden cut out.
In the mid part of the footprint are two features of interest. First is a small snail shell, which was picked up by the casting process and is evident in the cast itself. Second, and of more anatomical interest, is a clump of hard dirt or clay that can be seen in the photographs of the print before it was cast. This feature also is shown in the cast as a large hole protruding upwards into the cast itself. Could this shed some light on the bottom of the sasquatch foot? If this clump of dirt was present when the bigfoot made the print, then it was not broken apart by the weight of the creature. This would hypothetically be because the fat pad on the bottom of the sasquatch’s foot, yielded around the clump and didn’t exert enough pressure on it to break it apart (though the clump is visibly cracked along the left side). If the bottom of the sasquatch foot is this forgiving, so forgiving that it didn’t break apart a hard clump of clay, then it sheds some light on how these creatures can walk over rocks and other unpleasant things without causing themselves pain or discomfort.
Dr. Grover Krantz pointed out in his excellent book, “Bigfoot/Sasquatch Evidence” that the species seems to have a very thick padding on the bottom of their feet. He based this on observations of various footprints that contained the “mushroom effect” on the toes, as well as when individuals stepped on large rocks that would certainly have momentarily crippled a human.
Some might argue that the clump was introduced into the print after it was made, but there is evidence that this is not correct. The clump seems to be pushed into the substrate in the downward and forward directions, just the vector that would be expected from this situation. The clump seems to have discharged material laterally and upwards around it, just as would be expected.
If this hard clump of clay was to be stepped upon by a prosthetic foot of some sort, say a wooden cutout, then I believe the clod would have been obliterated and broken apart. I remember cleaning this cast, and that clump took some effort to break apart with the stream of water I used. I had to poke the dried clump with a piece of metal to break it apart before washing it away with water. It did not give up its shape easily. It is just this sort of material that might hold together when moist, even under the weight of a sasquatch, but only if the underside of the foot is soft and yielding. A hard surface would surely have destroyed this clod.
