Eh, why not spill it...
I've been wracking my brain, trying to remember exactly when this occurred. It was during my .410 bore phase, so I'd say it was about 10 years ago, occuring in Sand Canyon. To date, I've been hunting in this region for (scratches head and does the math) almost 30 years. With and without hunting buddies, w/ and w/o labradors.
At the time, I had parked my car at the trailhead, and walked in and upwards, about 5 miles to the beginnings of scrubby pines. At some point during the quail hunt, I paused on the edge of an opening located in a thin, frozen but sun-lit forest to mess around with my pack, my back to the open space. For some reason I turned around suddenly, and looked behind me. 50 or 80 yards behind me was a downed tree. It was one of those classic Sierra Nevada straight trunked trees, with no branches at all, near the base. It's diameter was about belt buckle high to a 6' man, and was resting flat on the ground.
Well, as I spun around, I saw a "hairy man" on the other side of that tree, watching me, sticking up almost 2' above the downed tree. He was just about the size of a 5 1/2' or 6' guy, and built real beefy, like a highschool football player. He had no neck. His big human shaped head sat directly on his shoulders. His fur covered him completely, and was about 3" long, and was so dark brown, as to appear blackish. This long hair didn't lay flat on his skin, but stuck out at about a 45 degree angle, exactly reminiscent of an orangutan. I don't recall making out any facial detail. It seemed to be way to shaggy to make out any detail on.
I have 20/10 vision, and for less than 10 seconds, I had a damn good (and also damned shocked) look at the upper 1/3 or 1/4 of his body.
As a hunter, I know that you will often walk past hiding animals, which then feel free to pop up when they think your back is turned, usually either to have a look at you, or more often, to flee and hide elsewhere.
His posture and attitude seemed to be one of, "well shit, how'd you know to turn around catch me looking?!" So, after several seconds of us staring at each other, he sinks straight down silently. For my part, my fear level and adrenaline are sky high. I'm standing there and saying to myself, "WTF was that?!"
Any time you find yourself saying that to yourself, you already know wtf that was, you are just in denial-- stalling for time, trying to get your scared brain to catch up to reality...
Tweren't no black bear, cat, nor person.
So, I stalled there after the sighting for almost a minute, trying to make up my mind what to do. Being somewhat young but plenty stupid, I then charged over to the tree, directly where it was standing, and bent over and looked over this 3' diameter tree (maybe 50' in length). The biped was long gone...
I honestly believe that it dropped down on all fours and hauled ass laterally in a monkey-like fashion and hid from me. The frozen dirt yielded no tracks that my scared brain noticed. At this point, I myself had had enough, and split, myself.
I'm easy to recognize in the hunting fields. I'm the guy who still bird hunts in this and other similar nearby canyons, but with a .45 along for company.
I told this incident straight up. It happened just like I say, w/o any exageration or embellishment.
