Bumpass Hell is named after Kendall Bumpass, a cowboy who was exploring the area in the 1860s when his leg broke through the crust and was scalded by the hot water. His story generated some interest, so a newspaper editor convinced Bumpass to guide him back to the area. This time Bumpass' leg broke through the crust again, and he ended up having it amputated.
