This is a nice group of divergent columnar Calcite crystals with cavernous centers filled with tiny rhombic crystals as is the outer "prism" faces. This occurence is noted in the Dal'negorsk book by the Mineralogic Almanac volume 4, 2001 titled "DALNEGORSK". A photo of this same occurence and habit is shown on page 47, in which it is described as "case-like". It quite fascinating and actually sits unaided straight up.

This specimen was personally collected by Robert Waidler in 1970. It is perfect, without damage, and with very thin iron oxide coating giving it a good orange color. The locality was formerly operated by the New Jersey Zinc Company and is located NE of Cuba City, east on Hwy 80. Dumps may still be available to dig.
