John Christian's Photo Gallery


Cragmont Mine, Cragmont neighborhood, Berkeley, Alameda Co., California, USA

Dimensions: 78 mm x 70 mm x 30 mm

This piece of cinnabar occurs in silicified and brecciated Northbrae Rhyolite. Noted University of California educated mineralogist, Charles Palache, found similar cinnabar in the Northbrae Rhyolite in this general area. Palache considered buying a very small piece of property containing the cinnabar from the giant parcel owned by a railroad company. Palache did not buy the property because it would be obvious that there was a mercury deposit once the owner went to the site.

Small quantities of cinnabar in Northbrae Rhyolite are found throughout North Berkeley.
