Crater Sulfur Mine | interesting place

 mine, interesting place

The Crater Mine has been mined for sulfur although significant amounts of gypsum and sinter are also present. The source of the sulfur is from hydrothermal alteration related to the vapor phase of a hot spring system feeding up through limestones and dolomites. Most of the bedrock in the immediate area is the Cambrian Bonanza King formation to the east and south with Cambrian Zabriskie quartzite to the west and Mississippian Perdido formation and Rest Spring Shale in fault contact in between. These relationships are dramatic as you continue north down the fault controlled Hanging Rock Canyon. There is a pull-out at 1.6 miles north of the summit. The outcrops are nearly all related to fault zones.

The mine and road leading to it are surrounded by park lands.
