Mystic Hot Springs near Monroe, Utah, developed from a natural hot spring long used by Indigenous peoples, including the Ute, Piute, Shoshone, and their ancestors, into a historic resort with baths, cabins, and a dance hall. Early settlers also stopped there along the Old Spanish Trail. Thomas Cooper homesteaded the property in 1886 and built a bathhouse in 1905, helping turn it into a developed destination. Later owners expanded its social and musical life, and concerts remained part of its identity. Its mineral-rich waters, shaped by activity along the Sevier Fault, formed the rust-colored travertine terraces that define its appearance.
