These unique crystals have a brown hourglass shape inside them. Surprisingly, we found many of them quite easily within the first foot of digging. This area of the state was also the location of strafing during World War 2, with planes flying through to practice their shooting and bombing. In fact, some the remains of some of those runs can still be found (As evidenced by the signage, however, anyone finding these things should retreat and call the authorities.).
Boy, does my back ache.
