Acres: 750,000

A rare look at the end result of volcanic activity that spilled lava across central Idaho around the time of Christ 2,100 years ago. Much of its terrain still feeling the effects of that event. Resembling that of a desolate distant planet. Its surface is rugged, black, and barren. Filled with basaltic lava and cinder cones. There is little topsoil and summer temperatures can reach 150 degrees Fahrenheit. The average annual precipitation is 18 inches or slightly above what a desert receives. Its hard to imagine life any harsher than at Craters of the Moon.

Sights along the 7 mile loop road (open from May through November) gives one the impression that you are entering a lifeless void. A landscape so similar to our planetary neighbors that it has been utilized by National Aeronautics and Space Administration (NASA) in training astronauts for walks on the moon.

The few plants that do survive include the rugged sagebrush and bitterbrush. Providing shelter for a number of birds and reptiles that have also adapted to this desert environment.

Mankind has always intrigued by how life adapts to the earth's extreme environments. Be it in the frigid Artic, dry Sahara desert, boiling hot springs of Yellowstone or here at these barren craters. Hoping to learn something that might help extend his own limits of survival or possibly bioengineer organisms that can survive the extremes of other planets.

Plants such as the sagebrush and bitterbrush are able to tap water deep in the soil by using their extensive root system that burrow up to 50 feet into the ground. Cactus survive by storing water in their tissues and having an impermeable outside tissue layer to prevent water evaporation. While other plants survive by having very small leaf surfaces. The part of a plant that loses the most moisture.

Craters of the Moon has 50 campsites at the park's campground which are open year-round. Crater's of the Moon National Preserve, PO Box 29, Arco, ID 83213 (208) 527-3257. www.nps.gov/crmo
