Homestead caldera

Homestead Caldera in Midway, Utah, is a geothermal hot spring enclosed within a natural rock dome and the largest mineral dome in the area. Estimated to be around 10,000 years old, it formed as mineral-rich water deposited travertine over thousands of years, creating a cavern-like interior. Water likely begins as rain and snowmelt in the Wasatch Mountains, descends deep underground, is heated, and returns to the surface, keeping the pool warm year-round. Once reached only through an opening at the top, it became publicly accessible after a tunnel opened in 1996. Today it operates as a commercial hot spring and dive site and has also been the scene of both archaeological recovery and tragedy.
