The History of Calcite Mine: High-quality calcite deposits were found here and the mine was built during WWII by U.S. government officials commissioned to find optical-grade crystals for gun sights and rocket launchers. The Polaroid Corporation bought the mine and employed several dozen men to mine the crystals until a synthetic replacement was invented.
The Pumpkin Patch is a geologic oddity of concretions. The is a vault toilet and picnic tables there. We’ll stop at 17 Palms and the mail box on the way out.
