>>5377095This is a pretty neat video.
I didn't bother to find the stuff he exactly talked about, but found some walls in a triangle, which look exactly like medieval ruined walls in France. Just north of the wall triangle are some more caves/crevasses, which look very much to me like the land itself is a megastructure that caved in.
I'd post to his youtube but I can't be assed to make a throwaway account.
It's probably Thule, homies.
