Death Valley Pupfish
In the midst of the Mohave Desert there is a small crack in the earth. This crack opens to an enormous flooded cave system called Devil's Hole. In this hole lives an animal that supposedly has the smallest distribution of any vertebrate species in the world - the Devils Hole Pupfish. Both the Hole and the Pupfish have always been sources of great interest. President Harry S. Truman made Devil's Hole part of Death Valley National Monument because of the unique geology and the irreplaceable fish. In the 1970's, water pumpers in the area, hoping to develop the desert for alfalfa production, were blocked by the U.S. Supreme Court when they were draining the fishes' habitat.
