Great Salt Plains
The Salt Plains are a flat expanse of mud, completely devoid of vegetation, located in north central Oklahoma. The name, Salt Plains, is derived from the thin layer of salt that covers the flats. This salt was used by Native American tribes and early pioneers who first settled the area.
The plains are 7 miles in length and approximately 3 miles wide and lie within the boundaries of the Salt Plains National Wildlife Refuge. The plains border the Great Salt Plains Reservoir, constructed by the U.S. Army Corps of Engineers in 1941.
When I was a girl, we'd go several times every summer to dig for selenite crystals because this is the only place in the world where you can find selenite crystals with a sand hourglass in the middle. We'd clean and shine our best crystals and clusters and take them with us on vacation to Colorado where this shop owner would buy them from us.
