Almost half a century later, in the winter of 1824-25, James Bridger, a trapper, discovered the Great Salt Lake while seeking the source of the Bear river.
"Jim" Bridger, a famous mountaineer and scout, saw the lake in 1824, apparently before any other white man.
Mormon migration passed along the trail in 1847-1849, and in 1853 fifty-five Mormons settled on Green river at the trading post of James Bridger, which they purchased and named Fort Supply.
A second group is typified by Palaeosyops, of the Bridger Eocene of North America; P. paludosus being an animal about the size of a tapir.
On the other hand, Palaeosyops is connected with Titanotherium by means of Telmatotherium of the upper Bridger and Washakia Eocene, a larger animal, with a longer and flatter skull, showing rudiments of horn-cores, only two pairs of lower incisors, and a general approximation in dental character to Titanotherium.
