Adaptive Management Strategy  About White Nose Syndrome Environmental Analysis

Cave registration & closures

Registration is required to access caves that are open. The registration system is designed to prevent authorizing access to caves that are closed based on the White-Nose Syndrome Environmental Analysis decisions or other considerations.

The White River National Forest also has caves that are closed year-round to minimize disturbance to bats. 

Review the Forest Order to see which specific caves are closed:

  • RO2-2019-01 Cave Access (.pdf)
  • Tongue River Cave Emergency Closure (Bighorn National Forest).
  • White River National Forest: Due to road closures associated with the Grizzly Creek Fire we are unable to issue any cave permits which are accessed from the FSR600 Coffee Pot Road or FSR400 Eagle-Thomasville/Crooked Creek Pass roads. This includes Fulford Cave, and well as several other caves in the area.”

Registration process

Select the correct registration form for the forest you want to visit:

Black Hills, Shoshone, and White River National Forests Cave registration form (.pdf). Save the form once you have it filled it out, then email as an attachment to:

Bighorn National Forest Cave Registration form (.pdf). Save the form once you have it filled it out, then email as an attachment to:

Note: The cave registration system involves submitting basic personal information (name, email address, zip code) and information about the cave trip (date, cave name, national forest, number of participants) online. Once the information is processed, an approved registration form will be provided to the person making the request (the “Trip Leader”). 

The Trip Leader is required to print and sign a copy of the approved registration form, and have each trip participant sign the form. Questions about the registration process can be emailed to the appropriate email address above. Reviewing the registration requests requires processing by Forest Service staff. Authorized registration forms are generally processed and returned to the applicant within 2 or 3 business days. 

Is it possible to gain access to closed caves?

For caves that are closed, the Forest Orders above include exceptions for research (Exception #5) and for members of the National Speleological Society and Cave Research Foundation (Exception #6) These exceptions are similar to those in place under the previous emergency closure. Under the adaptive management approach, exceptions will be made by the appropriate Forest Supervisor but are expected to be rare. Cavers are encouraged to visit these caves when they are open for public access.

Decontamination procedures following US Fish and Wildlife Service protocols are required by everyone to enter any and all caves. 

Decontamination refers to the process of cleaning clothing and equipment to prevent accidentally spreading the fungus that causes White Nose Syndrome. By properly decontaminating clothing and equipment, the likelihood of moving the fungus from one site to another is greatly reduced. 

A summary of the decontamination procedures is provided with approved cave access registration forms!
