Quartz on Rock
This was a piece of quartz on an separated bit of bedrock, below and visible from a bald spot of solid bedrock. It would have been visible looking outward from the bald spot. Two other times I saw a single rock on support rock made from quartz this way were in Harvard MA, where it was at the edge of a drop-off, and near Putney VT, just below a little lookout place and in line with a wall pointing to the horizon. So quartz in a rock-on-rock does occur but, maybe, for use at the beginning of a line of sight.
