The Great Salt Lake Basin is the largest basin in the Great Basin, surrounding the Great Salt Lake in Utah.

The Great Salt Lake Basin is the largest and most prominent basin within the Great Basin region. It covers a significant area, mainly in Utah, and includes the Great Salt Lake, one of the largest inland saline bodies of water in North America. This basin is endorheic, meaning water in the basin doesn’t flow out to the ocean but evaporates, contributing to the lake’s high salinity. The basin also features salt flats, wetlands, and unique ecosystems that support diverse plant and animal species, making it a distinctive geographical feature.
