Cripple Creek's District Museum Mineral Collection



Each month, for the past several years, I go twice  a month with two other scientists (Bob Carnein and John Rakowski) to catalog, photograph, and record detailed information on each specimen we work with. We donate our time to this important project. The Cripple Creek & Victor Gold Mining Company provided the funding for the archival materials that includes special paint and ink pens for catalog numbers, an ultrasonic cleaner, and other miscellaneous materials for the project. In addition to standard photographs of the specimens we work with, microphotographs are taken of certain specimens.I have a few microphotographs of selected specimens I would like to share with you.
