A pair of leaning triangular standing stones

This was on a sub-summit along the trail that starts near the southern end of Bragg Hill Rd in Westminster, on the way to Cowees Hill. It is a matched pair of triangular standing stones (really "leaning" stones) on either side of the trail. One, by itself, is an interesting "natural" feature. Two together is not natural, and so I suspect these are man-made deliberate structures. Here are closeups. The smaller one is obviously propped up:Perhaps the larger one was natural and the smaller was built in relation to it? This was one time when a compass bearing between the two would have been nice to have. They were roughly in an east-west alignment.
