Still photos were taken after they shot the footage, and plaster casts were made of the footprints. The distance between prints, and the depth of each impression indicate stride length and weight. print series casts have been taken on many other occasions, as shown in the book. These can be differentiated from the fake prints by the following observation:
> Evidence of a Midtarsal Break> Perhaps the most significant observation relating to this trackway was the evidence of a pronounced flexibility in the midtarsal joint. Several examples of midfoot pressure ridges indicate a greater range of flexion at the transverse tarsal joint than permitted in the normal human tarsus. This is especially manifest in the footprint figured below, in which a heel impression is absent. Evidently, the hindfoot was elevated at the time of contact by the midfoot. Due to the muddy conditions, the foot slipped backward, as indicated by the toe slide-ins, and a ridge of mud was pushed up behind the midtarsal region.http://www.bigfoot-lives.com/html/evaluation_of_alleged_sasquatc.htmlPic related.
Apparently they smell really bad, like garbage. When I am /out/ I am always evaluating smell, but have not noticed this yet. I live in sasquatch country.
