Quartz
Holmesville, Gage County, Nebraska, USA
Quartz crystals, 5.5 x 5.5 x 2.9 cm., crystals to 2.0 cm. These are fairly large quartz crystals for this area, and Nebraska in general. Specimens have been found in weathered geodes in the Permian sedimentary rocks around Holmesville. This one was probably collected by Scott Williams, and came to me from Dave Bunk. K. Nash specimen and image.
