Description

The Caverns of Sonora are famous for many The most famous single Helictite is named Butterfly of the Sonora after its characteristic form. Even rarer are the anthodites, which are found in this cave.

The visitors can choose between two tour. The Horseshoe Lake Tour covers the historic areas and the northern areas of the cavern. The Crystal Palace Tour is the longer one, including the Horseshoe Lake Tour. It also shows the Big Hilton Room, the passage up to Halo Lake, and the entire eastern branch of the cave, called Crystal Palace. There are also special tours available for groups of twelve or more by advance reservation. There is an educational tour for school classes or boy scouts and spelunking tours for the more adventurous and physically fit visitors.

During the development of the cave, tons of debris have been packed into pits and passages, to be out of the way. Since 1991 the Annual Caverns of Sonora Restauration Project once a year cavers remove some of the debris from the cave in order to restore its original state. So far (2005) 194 tons of debris have been removed, 139 tons alone from a shaft called Devil's Pit.

The Caverns of Sonora are unique, I know of no other cave in the world, open to the public which contain such a wealth of speleothems which can be seen at such close proximity to the visitor. Sadly this has resulted in some vandalism by the visitors.
