I had a similar-enough experience back in '88 at Babyfoot Lake in SW Oregon. My now ex and I left our 18 month old daughter with my ex's dad and step mom so we could celebrate our anniversary in the woods. We arrived mid afternoon after a 1.5 mile hike, set up camp, ate, then I took a few minutes to fish a little. The lake sits in a small glacial cirque. We were back near the headwall on a slightly brushy, timbered flat a couple acres in size. We heard rocks rolling far above us to the right. It was intermittent like something picking its way diagonally down and left across the headwall which was out of sight behind trees from us. We started to get weirded out, just felt .. "off", and after a big of discussion we thought we had enough time to get back to the truck before it was dark so we broke camp and hauled butt. The trail out crossed the ridge to our left from the perspective of facing the headwall, in other words, it crossed the ridge "it" seemed to be moving towards. Bit of concern whatever nameless "it" that it was would cut us off crossing the ridge. Now, I was packing a single action .44 and had a double action .357 my then wife was packing, but those didn't create any false confidence. We got to the ridge and it was already dusk-ish and dimming quickly. "It" wasn't waiting, though, so we headed up the trail toward the truck. A short ways up the trail there's a ledge the trail crosses which is a little snotty thing to get up especially in the dark. It's only waist high or so, just .. awkward. Once we were both up, took a couple steps, then the noises began. In those days, before the Silver Fire, the trail was a narrow slice through a sea of rhododendron and saddler's oak 10-15 feet high with douglas fir overhead. Pretty darn dark in there and a lot of cover within arm's reach of the trail so it was ... tense. Whatever it was, it stayed just above and behind us herding us like I've herded cows .. all about angles. At times we could see the rhodys and saddlers oaks being pushed aside and pushed down as something very large plowed through them. The cadence was of two feet. It was going through them like you or I would go through shoulder-tall grass .. seemingly little resistance to "it" though I do not think I could wade through it. Sometimes "it" seemed to stop making sounds. The first time or two, we thought maybe it left, but as soon as we would pass a small, more open spot, it would start up again, so it was leap-frogging ahead of us, then waiting 'til we passed it to begin "pushing" us again. It never got closer than 25-30 feet and was sometimes as much as 50 yards away. Once we got within a few hundred yards of the parking lot and truck, the cover thinned and it apparently stopped following.
My ex wife does not "believe in" bigfoot but now and then when that comes up in conversation her eyes get real big. She remembers that night .. well .. and has no explanation for what we experienced.
A year or so ago I talked to a local researcher just swapping stories and told him 'bout that hike. All he said was "Oh, you ran into HIM, yeah, he's a GRUMPY bastard."
Wish I had it to do over again but with someone else to share camp with, wouldn't wish that on my ex wife. I'd stay and see what happened. Nothin' ventured, nothin' gained. 30-odd years will change your perspective on things.
