Where to Find Halite in Utah

Utah halite is most famously the salt of the Great Salt Lake and its terminal evaporite deposits. The lake's south shore in Tooele County yields hopper-style halite crystals along the salt flats, especially after late-summer drying. The Salduro Marsh and Sevier Dry Lake in Millard County produce massive halite beds and large clear cubes. Paradox Valley salt anticlines in Grand and San Juan counties carry deep halite in evaporite sequences, and Bonneville Salt Flats in Tooele County is famous for its meter-deep salt crust used in land-speed racing. Surface halite is moisture-sensitive; specimens dissolve in humid air and need sealed display.

Standout halite spots in Utah

Hand-picked from the full list below, with the reason each one earns a trip.

Great Salt Lake
Tooele County County
The Tooele side of Great Salt Lake offers an unusual sediment specimen rather than a hard-rock target: oolitic sand made of calcium-carbonate coats around tiny nuclei in shallow, wave-agitated brine. UGS documents accessible oolitic dunes on BLM public lands at Stansbury Island and explains that Great Salt Lake sand is often chemically grown in the lake rather than washed down as quartz grains.
