Homestead caldera
The Homestead Caldera known locally as "The Crater" is a natural geothermal hot spring surrounded by a rock dome.What was once a refuge from a life of hard work in the 20th century has now become an attraction for snorkelers and scuba divers due to the perpetually warm water.Studies suggest that rain and snow melt in the nearby Wasatch Mountains percolated into the ground, descended along cracks and fractures to depths of one to two miles to get heated and then returned to the surface and depositing that material as travertine.Travertine is mainly composed of calcium and produces an abundance of white, porous lava-like rock that is very common in the Midway area.There is an ongoing archaeological project that works to retrieve items from the silt that have been lost or thrown into the crater over hundreds of years, including firearms and coins.
