🌬️ Tongue River Cave

Tongue River Cave is a cave in the Bighorn National Forest just west of Dayton, Wyoming, United States. 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".
