One of the best documented footprint finds was in Grays Harbor County, WA in 1982. Over a period of a few months, at least nine footprints were found and cast by witnesses, the local police, and a small number of bigfooters including Dr. Grover Krantz and Cliff Crook.
However, it has come to my attention that two very good quality replicas are being commercially and legally sold. The two casts in question come from the original molds made by Dr. Grover Krantz and licensed to Skulls Unlimited, a commercial fossil supplier.
The casts can be bought as a pair (click the picture or link above), or as individuals (click the picture or links below). There are other casts from this individual occasionally available from reputable sources at various bigfoot conferences across the country.
This track line also produced two half-casts from when the creature was running. One half-cast was taken back in 1982 and is well-documented in the literature, but the other and its recent discovery is documented on the DVD, Bigfoot Road Trip. Both half-casts are shown below.
A page in my bigfoot track database is long overdue for the footprint finds during this time, and one will eventually be added. For now, you can enjoy reading the report filed by the sheriff witness himself, Dennis Heryford, in the BFRO database by clicking this link.
