I am 3 for 3 this weekend - three sites found in three days of exploring. You see the same patterns over and over again: low ground piles with a piece of quartz, located along a stone wall; a split rock propped open by a rock with interesting crystals; a cracked rock with small stones covering the crack. Always where water is coming out of the ground. Over and over this weekend I found myself zooming in for a closeup of a single piece of quartz. In one place, I got lucky and found a view over water towards a prominent nearby mountain (Wachusett) and found something more elaborate, a multi-component site with some larger piles.
So I will be trying to get these sites off my camera and into this blog during the week.
