Crater Crawl - Run Around the Rings

Crater Crawl - Run Around the Rings Annual 10k & 2.9 mile trail run & hike @ Crater Rings National Natural Area, Mountain Home, Idaho

Participants will run or hike a challenging 10K (6.2miles) course that takes them around The Crater Rings, a unique site featuring one of the very few examples of volcanic pit craters in the continental United States, and thus recognized as a National Natural Landmark. The Crater Rings are adjacent, symmetrical volcanic pit craters, about 8 miles northwest of Mountain Home, Idaho. Situated at the

top of a broad shield volcano, the twin craters are thought to have once housed lakes of molten lava that belched violent fire fountain eruptions much like Halemaumau Crater of the Kīlauea volcano in Hawaii. The eastern of the two craters is about 3000 ft across and 350 ft deep; the western crater is 2500 ft across and 300 ft deep. The volcano is estimated to be less than 2 million years old, making it the youngest shield volcano in the area. The race course will follow a jeep road to the top of the shield volcano, then around the Crater Rings (see the course map below). Be prepared for some strenuous ups and downs (see the elevation profile below.) Adding to the challenge will be the desert heat, which is certain to conjure up images of the craters' ancient lakes of molten lava. Relief will come in the way of 3 hydration stations located along the course, the first at 2.1 miles, 2nd at 3.4 miles, and 3rd at 5.1 miles. Despite the challenges, this event is meant for anyone who might enjoy a supported outing in a very unique volcanic setting, whether they are a competitive trail runner, casual hiker, or anything in between. Purpose:

The goals of the Crater Crawl are to encourage the values of low-impact non-motorized outdoor recreation, raise funds for Idaho Outdoor Association projects. Online Registration: http://www.bluecirclesports.com/EventDetail_Sub.aspx?eid=1733

Standing at the crater's edge, you know this place has a presence. A breeze blows and you shudder. Is it someone who has passed before, or the crater itself, breathing and sentient? Should you run, or simply run away? Are you brave enough for Crater Crawl? There's only seven weeks left to prepare yourself for the inevitable. Sign up today.
