Jewell Cave National Park
53 miles southwest of Rapid City is the fascinating Jewel Cave National Monument. The names derived from it’s interior-a myriad of beautiful “jewel like” dogtooth and nailhead spar crystals. Interesting calcite formations may also be found, including hydromagnesite balloons, first identified here. With more than 73 miles of recorded passages, Jewel Cave is a giant underground labyrinth.
