The Sleeping Buffalo “springs” were discovered by a 1928 oil well, which intersected pressurized hot water and gas. This well was cased and left in place, and the 108 F water (with gas) flowed to surface at 700 gpm. A large resort complex was built around the well in the 1930’s and was a popular destination resort. A new well,“Legion Health Plunge 2A," was drilled in 1958 to a depth of 3,200 feet. This well (API 25071-06384) is completed in Mission Canyon Limestone.
