A former general manager of the Aladdin Hotel in Las Vegas, Bob Plummer, purchased a 100-acre (40 ha) parcel of land with an oasis of California Fan Palms (Washingtonia filifera) and natural hot springs.

During the 1970s and 80's he converted the property into a spa, resort and retreat enjoyed for over several decades by Las Vegas area families, with fond memories at the "Jewel in the Desert".

[1] The refuge was established to provide and protect the habitat of the endangered species of Moapa dace of which about 1,900 exist in the Muddy River area.
