Thermopolis

Geography

Thermopolis is located near the northern end of the Wind River Canyon and Wedding of the Waters, where the north-flowing Wind River becomes the Bighorn River, an instance of a river changing names at a point other than a confluence of two streams. The dual name is ascribed to the mountain barrier between the Wind River and Bighorn basins, obscuring the fact that the river that drains the two is the same. The term "Wedding of the Waters" dates to at least 1934, when a marker was placed at the location. Thermopolis is ringed by mountains, with the Big Horn Mountains to the northeast, the Bridger Mountains to the southeast, the Owl Creek Mountains to the southwest and the Absaroka Range to the northwest. Thermopolis is the southernmost municipality in the Bighorn Basin. Roundtop Mountain, on the northern edge of town, is a geological formation shaped much like a volcano. It sits at approximately above sea level and is the highest area in the immediate vicinity of Thermopolis. According to the Köppen Climate Classification system, Thermopolis has a cool semi-arid climate, abbreviated BSk on climate maps. The hottest temperature recorded in Thermopolis was on July 12, 2026, while the coldest temperature recorded was on January 16, 1930. |source 2 = National Weather Service }}
