Nutty Putty Cave
Nutty Putty Cave is a hydrothermal cave located west of Utah Lake in Utah County, Utah, United States. The cave attracted amateur and professional cavers alike despite its narrow passageways. The cave closed in 2009, after an accident that resulted in the death of 26-year-old John Edward Jones. Before that, it was popular among Boy Scout troops and college students.
