The Uses of Quartz
Native Americans quarried quartz from veins in boulders and outcrops. Some was used in arrowheads, some was used to mark sacred places such as burials. Here the quartz has been nearly completely removed from the vein in this outcrop. These photos were shown on Larry Harrop's blog two years ago.
Quartz is often incorporated into stone walls, and may be decorative, as well as an aid to night travel. Sometimes these stones occur at regular intervals in walls.
This practice may have been carried into historic times. Here is a large chunk of quartz left in the wall of a cemetery at a revolutionary war site.
