The Timpanogos Cave National Monument is a network of Grotte S located in the Montagne Wasatch close to American Fork in the Utah at the the United States. After a rather difficult walk of 2 kilometers on a track paved to the side of a mountain, the entry with the cave is accessible. The visits take place during the opening of the monument, from May to October.

There are three accessible principal cavities during the visit: Hansen Undermines, Middle Cave and Timpanogos Cave. One can see many single and coloured speleological phenomena there. Among most interesting, the Hélictite S resemble straws of rock. It is thought that they are formed when water crosses the tube then evaporates by leaving a light mineral deposit to the end. Other speleological phenomena are present: underground columns, run calcite, Stalactite S and Stalagmite S.
