Utah's other Great Salt Lake is underground, ancient, deep....and fresh‎

Under the Great Salt Lake playa lies a potentially vast reservoir of pressurized freshwater that has accumulated over thousands of years from mountain-derived snowmelt, according to new research from University of Utah geoscientists. This groundwater occupies the pore spaces in sediments that fill the basin west of the Wasatch Mountains and below a 30-foot-thick salty layer.
