Craters Of The Moon National Monument

Custom Search

Established in 1924, Craters of the Moon National Monument celebrated its 75th birthday in 1999. On November 9, 2000, President Clinton issued a proclamation greatly expanding the size of Craters of the Moon National Monument and designating that it be cooperatively managed by the National Park Service and the Bureau of Land Management. The Craters of the Moon (COM) lava field covers 618 square miles and is the largest young basaltic lava field in the conterminous United States. The park contains more than 25 volcanic cones including outstanding examples of spatter cones. There are 60 different lava flows in the COM field and they range in age from 15,000 to just 2,000 years old.

The Kings Bowl and Wapi lava fields, which are about 2,200 years old, are also now part of the monument. All 3 lava fields lie along the Great Rift, with some of the best examples of open rift cracks in the world. There are excellent examples of pahoehoe, slabby pahoehoe, shelly pahoehoe, spiny pahoehoe, aa, and block lava, as well as rafted blocks, tree molds, lava tubes, and many other volcanic features.

Although a desolate looking place at first glance, the Monument thrives with wildlife. More than 370 species of plants and 51 mammals have been be found in the Monument and more than 170 different species of birds have been seen here. A 7 mile loop drive at the north end of the Monument provides unique views. Hiking trails range from 1/4 to 11 miles round trip.
