Apologies if this is a stretch, but I found something while hiking near Loch Katrine in early November that's been bothering me. I was out doing a solo hike, exploring some of the less-travelled paths on the north shore. There's a boggy area about half a mile from the main trail where I found what looked like substantial footprints pressed into the mud.
They were roughly 13-14 inches long, with what appeared to be a heel impression and five toes. Much larger and differently shaped than a human foot, but clearly bipedal. The prints went about twenty metres before disappearing into rockier ground. I took photos and measurements at the time, though I'm embarrassed to say I didn't photograph them brilliantly. The light was failing and I was honestly quite spooked.
I know the rational explanation is probably a large human, a bear, or something I'm misidentifying. But the gait pattern suggested something unusual - the stride was longer than you'd expect for a human of any size. And there's no established bear population in Scotland, so that seems unlikely. Anyway, if anyone's interested in looking at the photos or discussing what this might be, I'd appreciate it.
