Located in American Fork, Utah, about 30 minutes south of Salt Lake City. The site preserves a limestone cave formation discovered in 1913. It is unclear if Native Indians were aware of this site.
Pro Tip: The site requires timed reservations. Check recreation.gov and but tickets prior to heading to the site only to find it sold out. Also, the cave starts at the top of a mountain. The 1.5 mile hike is aggressive in elevation. People with health conditions and children should be aware, though there are benches to rest along the way and you have 1.5 hours to complete the hike before your tour starts.
