Crater Rings are adjacent, symmetrical volcanic pit craters in the Western Snake River Plain about 8 miles northwest of Mountain Home, Idaho.  They are one of few examples of volcanic craters in the continental United States.  The craters are at the summit of a broad shield volcano. The eastern crater is about 3000 ft across and 350 ft deep.  The western is 2500 ft across and 300 ft deep.  The craters are probably former lava lakes similar to Halemaumau Crater of the KÄ«lauea volcano of Hawaii.  The volcano is the youngest of the shield volcanoes near Mountain Home and is estimated to be less than 2 million years old.  Crater Rings are a National Natural Landmark designated in 1980.  The site is owned by the Bureau of Land Management as part of the Morley Nelson Snake River Birds of Prey National Conservation Area.

I visited this site on June 2.  It is not easy to get to because there are not any marked roads.  To help others, I have posted my GPS tracks along with a description of how to get to this site in the route library at this site.

 Trent talked me into not using the GPS and taking a short cut across the desert to get here.  That's why we call this Adventure Sport Riding!
