Niter Ice Cave
Just past the town of Niter, a 100 yard detour to the east will lead
travelers to Niter Ice Cave. The Niter Ice Cave was used by early
pioneers as a year-round refrigerator, keeping a temperature dozens
of degrees cooler than outside. The Cave was formed when basalt lava
flowed out of a vent 500 thousand years ago forming a lava tube
typical to this type of volcanic activity on the Snake River Plains.
The Niter cave is actually a piece of a lava tube system that would
have gone on for miles thousands of years ago.
This Cave was important to early settlers and native
Americans for food storage. John A. Dalton, the original
homesteader, and his family used the Cave for that purpose as well
as a refuge from encounters with unfriendly native Americans.
