I was hunting high up in the Bitterroot mountain range on the Idaho side with my Father in Law and had found an area where there was a forested draw where we could see that the Elk liked to lay up out of the sun.
We figured it could be a nighttime sleeping area. We devised a plan where I would hike up to the ridge overseeing the draw and as the sun barely started to show I would slowly low crawl down the side of the ravine and try to spook the Elk to head up the ravine where my Father in Law was waiting.
I started low crawling very slowly and silently down the side of this ridge, head first, terrified I might bump into a cougar, which are everywhere up there. The grass was very wet with dew and I was soon soaked as I approached the bottom. I must have made a noise or got winded by the rising air because suddenly I heard a heavy thumping of something running up the draw right in front of me that I could tell was not four-legged, and it was alone.
A minute later I was at the bottom and the sun was brightening and I looked at the ground and didn't see any Elk tracks anywhere. I thought maybe a bear, but no bear tracks. It was still too dark to really make out anything distinct so I waited a bit until I could see. As things brightened up I noticed that something with a long gate had run up the ravine, but the ground was hard from all the Elk traffic that had beat the dirt down hard, so I couldn't make out what it was at first. I started tracking up the ravine and in the distance about 50 yards I could see where whatever it was had cut up the hill because the dew was freshly disturbed and I could make out a dark path of grass with no dew heading up the hill.
When I got to the path it only took me a step or two to see big huge bipedal footprints with distinct toe outlines digging into the side of the hill and mud coming out around the toes as it raced up the ravine away from me. By the size of the prints it wasn't a full grown one, but maybe a young adult or juvenile. Putting my size 10 boot next to it was nearly double my length. When I realized that I had slowly crept up on a Bigfoot it left me a bit unnerved. I wasn't forty feet from it when it bolted.

Twice the size of a size 10 boot sounds huge. It was more than likely an adult Sasquatch.
The famous deadly Bauman Bigfoot encounter happened near the Idaho & Montana boarder of the Bitterroot Mountains too, along with many more bigfoot sighting reports.
