3811034
location:
Elk Creek, Meade Co., South Dakota, USA
description:
Exceptional unusual and rare cabinet piece for this locality, a cluster of what were once whewellite crystals to 9.0 cm in length across the front of this matrix and replaced by colorless crystallized calcite. Along the left side of this is a light amber colored grouping of non-altered whewellite crystals. The piece has been repaired, where I cannot tell. The repair is done very well. Quite rare.
