In southern Idaho and to the southwest of Yellowstone National Park, PROBA-V spotted the Craters of the Moon, a United States monument and nature preserve. In the false-colour image, the preserve is shown prominently in dark brown, surrounded by agricultural fields in scattered red. Formed over thousands of years by lava eruptions along the Great Rift, with the most recent one occurring 2000 years ago, Craters of the Moon provides a unique landscape with a mixture of lava flows, cinder cones and sagebrush. The geology of the area, resembling the volcanic surface of the Moon, has inspired trainers and educators for many years. Not in the least from NASA, when it trained the Apollo astrounauts to walk on the natural satellite and compagnon of our Blue Planet in the 1960s.
