The Niter Ice Cave is a geological feature approximately 3 miles south of the small southeastern Idaho town of Grace, Idaho.
The most probable explanation for the Niter Ice Cave is that thousands of years ago, a volcanic eruption formed a huge lava tube that eventually cooled to form this cave. Early settlers in the area found the cave a great place to store their food and collect ice all year around. It was and still is a favorite picnic spot and recreation site.
In most recent years, there have been explicit drawings and graffiti on, around, and in the ice cave.
