Henke Shoots for the Moon

Craters of the Moon National Monument and Preserve is a U.S. National Monument and national preserve in the Snake River Plain in central Idaho. The Monument and Preserve encompass three major lava fields and about 400 square miles (1,000 km²) of sagebrush steppe grasslands to cover a total area of 1,117 square miles (2,893 km²). The Monument alone covers 53,571 acres (21,679 ha). All three lava fields lie along the Great Rift of Idaho, with some of the best examples of open rift cracks in the world, including the deepest known on Earth at 800 feet (240 m). There are excellent examples of almost every variety of basaltic lava, as well as tree molds (cavities left by lava-incinerated trees), lava tubes (a type of cave), and many other volcanic features.^[5
