Homestead Crater

The Homestead Caldera, known locally as "The Crater" is a natural hot spring surrounded by a rock dome. It is located in Midway, Utah. It is a commercial location open year round to scuba divers and swimmers. Originally, it was accessed from a large natural opening at the top of the dome, but has since had a tunnel blasted through horizontally for easy access. The Crater began forming 10,000 years ago, and is made of minerals deposited by the rising, heated spring water.

It was used in the Danny Boyle film 127 Hours as a shooting location. The film portrays it as existing 300 miles south of its actual location, in Blue John Canyon.
