1882discovered by gold seekers.

Description

Black Hills Caverns has an astounding variety of formations. You will see  stalagmites,  stalactites,  helictites,  boxwork, logomites, frost crystal, purple amethyst, dog tooth spar crystal, cave flowers, nailhead spar crystal, popcorn crystal and much more! Many of those speleothems are descibed in our  speleothems section, but some are pretty rare.

Logomites (aka snurds) are special stalagmites which were first discovered, described and named in the Black Hills. They are also found in other caves, especially in remote parts of Jewel Cave. This are tall spires, between five and ten centimeters in diameter, and up to two or three meters tall. They are not stalagmites, as they are coarsely crystalline and not layered and generally have a large vertical hole which means they are hollow. But this is not visible from outside, the main impression for the visitor is the crust of socalled popcorn calcite they are covered with inside and outside. There is so far no satisfactory explanation how they formed.

Frostwork (Anthodites) are needle-like crystals usually found in radiating clusters. Thy have a diameter of severl centimeters, but the cluster form cluster which may cover huge parts of the cave wall. The individual crystal is only a few millimeters long, clear, white, or tan in color and varies in thickness between less than a millimetre and up to two or three millimeters. Frostwork is not calcite but aragonite, which has the same chemical fomula but a different crystal structure.
