The refuge was created on June 18, 1984 to protect an extremely rare desert oasis in the Southwestern United States. It is administered by the U.S. Fish and Wildlife Service.[1]
Ash Meadows provides a valuable and unprecedented example of desert oases habitats, that have become extremely uncommon in the southwestern deserts. The refuge is a major discharge point for a vast underground aquifer water system, reaching more than 100 mi (160 km) to the northeast. Water-bearing strata come to the surface in more than thirty seeps and springs, providing a rich, complex variety of mesic habitats.[1]
Virtually all of the water at Ash Meadows is fossil water, believed to have entered the ground water system tens of thousands of years ago.[2].
Numerous stream channels and wetlands are scattered throughout the refuge. To the north and west are the remnants of Carson Slough, which was drained and mined for its peat in the 1960s. Sand dunes occur in the western and southern parts of the refuge.
At right is an example of the mortar and pestle grinding holes. A well constructed boardwalk provides a pathway for visitors and protects this fragile habitat of the area. There are 26 varieties of plant and animals found here that are
endemic to the area, meaning they are found nowhere else in the world.
The very small pupfish are a vibrant blue, seen darting in the pools along the boardwalk.
It was a very interesting day, a place we will surely revisit.
