The real explanation for most “unexplained” shit is that sometimes weird shit happens or people act stupid and it has nothing to do with the supernatural.
An area a kid can’t climb to is probably more likely an area where a kid can’t climb to -safely-. When I was a dumbass 12-year-old kid who didn’t understand EROSION BAD, I climbed on top of one of these things. Took me no time at all to get up, and I could gave kept going if there was more to climb. If it wasn’t a tourist trap and I was wandering around alone I might have gotten stuck at the top, died, and I’d be an entry for the dude’s book.
That’s just that one specific thing, but I’m sure we all have a story of some stupidass shit that happened, particularly if someone’s panicking.
Also, I’m sure people get murdered innawoods all the time for all sorts of reasons. Doesn’t mean they’re all connected.
