Calaveras River Canyon, Valley Springs area, Calaveras Co., California, USA
Photo: 2010 Jake Harper
Quartz crystals from the Valley Springs area are most sought after for their beautiful lanscape-like inclusions of Epidote, Chlorite and altered matrixes in various combinations. Pockets are located in Lateritic soils derived from the decomposition of greenstones and metasedimentary rocks. These pockets are almost always completely collapsed - their contents sometimes scattered for several feet. It is unfortunate that this unique locality is closed to collecting due to large sub-divisions devouring productive areas.
The occurrence is located in and around the Calaveras River canyon approximately 8 miles west of Valley Springs.
