A guided day on the Bonneville Salt Flats west of Salt Lake City: how evaporite basins cycle, why halite grows stepped hopper faces, and careful crust-sampling technique that leaves the racing surface untouched. Operates under the Heat, Hydration, and Desert Fieldwork Standard — there is no shade out there at all.
Before you go
This trip runs entirely under the heat standard: a gallon of water per person, hourly buddy checks, and a hard turnaround time that does not negotiate with "just one more crust." Bring eye protection — the glare off the flats is its own field hazard — and review the halite sheet so the hopper crystals get the appreciation they deserve.
