JOINT
VENTURE AT CRATER RINGS
Crater Rings are two closely adjacent pit craters that provide one of the few examples of
this type in the continental United States. The crater rings are larger than, but similar to, pit craters along
Chain of Craters Road on the southeast flank of Kilauea Volcano, Hawaii.
The Crater Rings were a large summit caldera that originally contained a lava lake. Higher
elevation ramparts were formed by fire fountain eruptions that threw spatter and bombs out of the pit crater.
Pit craters are volcanic conduits in which the lava column rises and falls. These craters
were formed by explosions followed by collapse. Crater Rings are on the National Registry of Natural Landmarks.
Idaho has several natural landmarks on the registry.
This cache was created by the efforts of several Geocachers who without meeting, chose the
location, set the log book and container and stocked it with trading items. Thanks to vino3, rcracer, and Seth!.
