Various minerals, such as gemmy quartz (to 6 inches) and the famous amethyst scepters (to 8 inches), may be found here.
The locality produces a variety of minerals in different quality. Top-notch striated, lustrous, and clear quartz crystals 3-4 inches long have been found, but most are dull or milky.
Amethyst occurs as scepters, or more commonly as scepter heads that broke off and healed while loose in the pockets.
Most crystals are found loose in soil, long weathered out from pockets deep in. Occasional discoveries are made in breccia boulders.
