For hunters, trappers, and wildlife biologists such as myself, tracks are the best form of evidence for the existence of a mammal species in an area. Since most North American mammals tend to be elusive and nocturnal in their habits, their tracks may be the only way of knowing that they occur in an area. In the case of the sasquatch, tracks left by its passing constitute a form of evidence that I find hard to refute.

Although descriptions of tracks are helpful, the value of track reports increases significantly if good photographs are taken.

Even better than photographs are plaster casts. These show details of  foot anatomy and, if the soil is fine enough, even the dermal ridges of the skin on the sole.

On the basis of his collection of photographs and casts of over 100 different sasquatch tracks, anatomist Jeff Meldrum of Idaho State University has been able to provide a detailed explanation of the anatomy of the sasquatch foot. We can safely say that we know more about the sasquatch foot than any other part of its anatomy on the basis of the many tracks photographed or cast.

(Jeff Meldrum explains that "short toed" tracks such as these are actually the result of the sasquatch holding its toes in a tightly-curled position.)

Photographs and casts reveal that sasquatch tracks, although they superficially resemble large human tracks, actually have a number of differences. These include their arge size (up to aprox 20 inches in length and, even more importantly, up to 12 inches in width across the toes), and different proportions (normally approx 1/3 wider than human tracks of the same length).
