1998, Marble Mountain Wilderness, California: Man Collects Bigfoot Scat
One of the only known samples of Sasquatch scat collected in the wilderness was reported by Walt Peterman of Santa Cruz, CA. While Mr. Peterman was vacationing in the Marble Mountains, he went of a long multi-day hike. On the third day of his trip, he awoke to the worst smell he ever smelled.
When he investigated the odor’s origin, Mr. Peterman discovered a large pile of poop near his campsite. It was unlike any pile of poop Mr. Peterman, an experienced outdoors man, had ever come across. He immediately found a container to collect a sample.
As he hiked out of the wood, Mr. Peterman was convinced he was followed. He heard weird noises – howls, tree knocking, and snapping of branches – behind him. On the night before he reached his car, his campsite was attacked. His tent was ripped, his supplies eaten, his belongings scattered around the area.
After several hours, Mr. Peterman was able to collect all his things. With the notable exception of the container which contained the Bigfoot scat sample. Mr. Peterman remains at a loss as to what attacked his campsite or why they would have absconded with a poop sample.

“On the night before he reached his car, his campsite was attacked. His tent was ripped, his supplies eaten, his belongings scattered around the area.”
That sounds like a bear attack. The Marble Mountain Wilderness is inhabited by American black bears that will attack unprotected food stores. I would expect “an experienced outdoors man” would know how to store his food properly. Mr. Peterman was lucky he wasn’t injured.
When Mr. Peterman’s tent was ripped, was he inside it at the time? If so, surely he would have seen the attacker. Otherwise, it sounds like he left his camp unattended with food in and around the tent. Again, any experienced backcountry hiker should know better.
All animals produce scat in the forest. What makes Mr. Peterman certain this particular scat was produced by a primate not yet known to exist? Why not bear, mountain lion, coyote, or any other large mammal capable of produce similar looking (and, I imagine, equally foul smelling) scat?
I wish it were a Sasquatch, but that conclusion seems like a huge leap from several more likely possibilities.
