Cave Register Program

The Cave Register program is maintained by the Oregon High Desert Grotto. Registers are used to document cave visitation. They are placed inside the cave and include a container with a notepad inside for people to write in the date of their visit. Not all of these registers are maintained by the Grotto, as some have been placed by other entities. Generally, leaving anything behind in a cave is frowned upon, but sometimes a register is used to document cave visitation to see how much impact the cave is receiving, as well as to allow visitors a way to "leave their mark" that doesn't harm the cave.

These are the caves with known registers in our area:

  •  Honeycomb
  •  Super Rat
  •  Keyhole
  •  Bat Crack
  •  Owyhee River
  •  Fortymile
  •  Tire Tube
  •  Lower Perry
  •  Cliff
  •  Battle Axe Mountain
  •  Crack of Doom



The Oregon High Desert Grotto is an internal organization of the National Speleological Society. We are dedicated to the study and preservation of caves.


Membership in the Grotto is $15 a year and comes with an invitation to the Google Group forum, access to the Grotto library, issues of the Oregon Underground newsletter, and information on yearly caving activities and trips.
