|Elevation Change:||+940' net elevation gain|
Note: Mallory Cave is closed until further notice. The trail remains open, however, the cave itself is not open to the public. The closure stems from an epidemic of white-nosed syndrome, a fungal disease that has destroyed bat populations across the country.
The U.S. Forest Service closed all caves on National Grassland and Forest properties across several states in an attempt to limit the potential for spread in the Western region. Because the disease is primarily found in human-accessible recreational caves, people are thought to be the main cause of spreading.
- The final ascent to the cave can be difficult under wet or winter conditions. Proceed cautiously.
Rules and Regulations
- Mallory Cave is closed to the public to help prevent the spread of white-nosed syndrome. Please honor travel and access restrictions in the cave vicinity.
