I just finished reading chapter six of Joel Hardin's book Tracker, which is entitled "Tracks of Bigfoot".
The chapter covers his on scene investigation of tracks in the Mill Creek watershed near Walla Walla Washington in June 1982. I believe his conclusions have been summarized elsewhere, but the particular details are interesting.
One paragraph on page 132 is telling:
"I finished the cut and then re-cut a few areas. I was positive that this area would have shown any tracks going through it - in fact there were several small animal prints visible - but Mr. Bigfoot had not ventured this way. Nothing as large as a fox could have come through there in the several weeks previously without leaving obvious prints in the vegetation. When I finished the sign cutting, I again stood at the spot I'd left my shirt. I'd made a complete circle and found no sign larger than that of a deer entering or exiting the area from any point. All of the prints that this particular Bigfoot had made were contained within that small section. I counted the prints again: eight, well possibly nine, counting the scuff marks on the trail. If a Sasquatch had made these prints, it would have to have floated in, hit the ground walking for eight or nine steps, then floated away again."
Page 140 contains comments specifically about Paul Freeman:
"Several times between the 1982 sighting in the Mill Creek watershed and 1994, Paul Freeman was involved in other Bigfoot sightings, including on in which he reported having seen a family of the creatures, including a male, female and offspring. Local sheriff's deputies, searching the scene of the sighting, discredited this report and confronted Freeman. He admitted to authorities that he had not only made up the story but had constructed some "feet" to make tracks as evidence to validate his sighting and had done so in previous events."
"Rene' Dahinden died in 2000 and Grover Krantz died in 2002, having never resolved their argument regarding the Freeman Blue Mountain sighting."
"These episodes created for me a whole new awareness of the Bigfoot phenomena. I still haven't seen Bigfoot footprints that I believed were real, though I have to date looked at a number of very, very good hoaxes. Universal Tracking Services was contacted by Peter Byrne of the Bigfoot Research Project in Hood River, Oregon. This was a research group funded by the Academy of Applied Sciences to locate and secure evidence of the existence of such creatures in the areas where reported sightings were most numerous. I, in company with other UTS instructors, accompanied research personnel on several excursions to look for and examine prints found at reported sightings. This research project ended in 1998 without finding evidence of the existence of Sasquatch or validity to any alleged Bigfoot footprints or any reported sighting of the creature."
