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. The most productive ground is in Great Salt Lake south shore (Tooele County), Salduro Marsh (Millard County), Sevier Dry Lake (Millard County).

Casual hand collection of common rocks and minerals like halite is allowed on most BLM and U.S. Forest Service land in Utah, with daily and annual limits set by the local field office. National parks, most state parks, and tribal land are off-limits. Always confirm rules before a trip.

Great Salt Lake south shore (Tooele County) is the standout. Other strong ground includes Salduro Marsh (Millard County), Sevier Dry Lake (Millard County).
