Description

Spirit Mountain Cave is a so-called beginner cave, a wild cave which does not require technical skills and is frequented by spelunkers. It is located on Cedar Mountain overlooking the resort city, west of Cody. The cave is developed on three levels and mostly narrow. Vertical gear is not necessary, but the levels ar connected by vertical shafts and handlines are highly recommended to climb them.

The cave was discovered in the early 20th century by Ned Frost while hunting mountain lions. One of his dogs chased a catamount into the cave entrance, when he followed he discovered the cave. The cave was named Frost Cave, after the discoverer.

At this time William F. Cody, better known as Buffalo Bill, often posed with tourists at the mouth of the cave. He convinced President William Taft to declare it a National Monument. The cave was renamed Shoshone Caverns.

In order to commercialize the cave, the monument designation first had to be rescinded. This happened in 1954 and the cave was handed over to the city of Cody who started the development The cave was renamed Spirit Mountain Cave after Cedar Mountain, the place where it is located, which is also known as Spirit Mountain. In 1957 the cave was opened to the public, inaugurated by Wyoming Gov. Milward Simpson. It had trails, concrete steps and electric light, some remains of the trails can still be seen. The road to the cave entrance is a result of this development. But the cave was never a success, it was to far away and the road too narrow and difficult. Changing the management did not solve the problem and finally the cave was closed in 1966, after only 9 years of operation.

The cave has interestng speleothems, which are a result of its formation. The rocks of Spirit Mountain are partly of valcanic origin and there is still some volcanic heat. The ground water is heated and contains sulfur, which is tranformed into sulfuric acid, which speeds up cave formation. Many caves in the area contain sulfur related gasses, many of them are poisonous, so some caves were closed by concrete walls. The minerals in the cave are often gypsum, a result of the combination of calcium carbonate (the limestone) with sulfur. Spirit Mountain Cave is said to contain fluorescent cave minerals.

Because of a rockfall in 2012 the cave is currently closed. It might be reopened after the dangerous debris has been removed by volunteers.
