Colter's Hell is a mostly inactive geyser district located just west of Cody, Wyoming, at the mouth of the Stinkingwater River Canyon
While geyser activity has been minimal in recent times, there are accounts of geothermal activity similar to that inside the boundaries of Yellowstone National Park in the not too distant past.
John Colter, an intrepid member of the Lewis and Clark Expedition, gave the first accounts of the area to non-native Americans following his solo journey of 1807-1808. But Colter's descriptions of gloomy terrors, hidden fires, smoking pits, noxious streams and the all-pervading smell of brimstone were too wild for his listeners to believe. They derisively dubbed the imaginary place "Colter's Hell."
