On Wikipedia

Tongue River Cave is a cave in the Bighorn National Forest just west of Dayton, Wyoming. Historically notable for a wide variety of rare cave formations and animal species, the cave has suffered in recent decades from unrestricted traffic, vandalism, and the theft of many of the cave's speleothems. Deemed beyond preservation, the cave is now managed by the U.S. Forest Service as a "sacrifice cave". The Big Horn National Forest closed the cave to the public in July, 2010 to prevent the spread of White nose syndrome, however the cave has since been reopened.
