It has an entry slope called the Stonewall. They contain eleven different minerals including sphalerite which is the main ore mineral. The calcite is a common gangue mineral associated with the sphalerite. This specimen is a translucent to transparent double terminated complex calcite crystal resting on a secondary crystal. The upper termination has a slightly cleaved and healed surface which is typical for the calcites from this locale. The secondary crystal has a cleaved/healed base and the termination has fluorite crystals attached. There are inclusions of chalcopyrite present.
