I followed the serpentine row that turned into a zigzag row, which led to other zigzag rows that bordered the riparian zone of water features. Some ended at springs, some at swamps. In one swamp in particular, there were stone mounds and boulders with other stones on them. The most striking was one that looked like a Bear’s Head:
It took a while to realize that the stone beside the obvious bear’s head (which is balanced on the stone and will rock when touched) was a fire starter base with pits worn in it with a drill type fire starter. A shell fits the contour of the base stone and burning tinder can be swept into the shell, filled with tobacco. The shell fits neatly into the depression on top of the bear’s head.
There’s a similar Deer’s Head Stone on a boulder nearby, as well as piles of stone and some zigzag stonework inside the swamp also. So I started following water features and stone rows, looking for more mounds and boulders and apple trees. There is a huge mound of stones east of the bear and deer, a valley and a hill away. I crossed a town line to get to it.
