The Carrizozo Malpais runs 44 miles through the Tularosa Basin in southern New Mexico. The lava flow is the result of the eruption of Little Black Peak between 1,500 and 2,000 years ago. The flow is between 2 and 5 miles wide and is 165 feet deep at its thickest point. It is one of the youngest and best preserved lava flows in the continental United States. Photo taken 9/2/07.
