(Historic) Lyle Laverty
On Monday, October 23, 1967, Lyle Laverty and his marking crew from the Six Rivers National Forest visited the Patterson-Gimlin film location. The crew, who had been working on a timber sale, had been camped nearly all summer just downstream from the site at the junction of Notice Creek and Bluff Creek. They learned about the event while in Orleans for the weekend. After their arrival, Laverty followed the tracks of a single individual along the sandbar for several hundred feet. He took color slides of the ostensive sasquatch tracks and noted that some had been cast. One of his pictures, known as the Laverty Print, shows what has been described by Jeff Meldrum as a mid-tarsal break.
Before retiring from the U.S. Forest Service, Laverty was the Regional Forester for the Rocky Mountain Region, based in Denver. Laverty came out of retirement to become the Director of State Parks for Colorado. On Friday, 05 October 2007, Laverty was confirmed by the U.S. Senate for the position of Assistant Secretary of the Interior for Fish, Wildlife and Parks.[1]
There appears to be some debate that Lyle was rather corrupt, read about it at the link here. And here.
