Crater Crawl - Run Around the Rings

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
