Next Best 100: #66 Explore an ice cave
Ice caves are caverns in limestone rock that stay cold enough to contain ice all year long. Water seeping into the caves freezes in columns or spreads across the floor to make an ice-rink-like surface. The most accessible caves are on the Ice Caves Loop in the Big Snowy Mountains Wilderness, and Big Ice Cave and Crater Ice Cave in the Custer Gallatin National Forest.
When: July through September.
Where: The Ice Caves Loop is in the Big Snowy Mountains, 10 miles south of Lewistown; Big Ice and Crater Ice caves are in the Pryor Mountains about 50 miles east of Red Lodge in the Custer Gallatin National Forest.
