These rings were pretty cool. North Crater in background. With as windy as it was, I'm surprised those rocks were enough to hold down the teepees.

Teepee rings, or stone circles, left behind by the Shoshone-Bannock people are among the most visible archeological artifacts at Craters of the Moon National Monument and Preserve. These circular rock formations were used to weigh down the edges of skin-covered teepees and can be found along the trail near Indian Tunnel.
