The Great Salt Lake is a lake in the pre-War state of Utah that has Salt Lake City and New Canaan on its coast. This area is also mentioned as being a known territory of the White Legs. In 2277 Ulysses is sent to the Great Salt Lake to rally the White Legs against the New Canaanites in hopes of killing Joshua Graham. By 2281 New Canaan, a town north of the Great Salt Lake is destroyed. In the same year the Courier goes on an expedition with Happy Trails Caravan Company to Zion Canyon.
