This is the second volume of Irving's The Rocky Mountains...Adventures in the Far West. Irving's accounts made famous Captain Benjamin Bonneville's explorations in the American West (1832-35). The expedition sought information about the Oregon Country, which at the time was jointly occupied by the United States and Britain and largely controlled by the Hudson's Bay Company. Even though he was unable to complete his goal of reaching the Willamette Valley, he and members of his party were able to gather invaluable information on the region and blazed portions of both the Oregon and California Trails. The map included as the frontispiece to this volume is:

Map of the Territory West of the Rocky Mountains. This map extends from Monterey, California to Cape Flattery and inland to Flathead Lake in today's Montana. The Great Salt Lake is named Lake Bonneville, with no mention of Utah Lake. The map locates and names the Salmon, Boise, Malade, Snake, Columbia and Flat Head Rivers. Several dead-end rivers and lakes are shown in the Great Basin area including Lost River, Ashley's Lake, Battle Lake, and the Mary or Ogden's River. It describes the territories of the Shoshoco, Eutaw, Too-el-Iican, Skynses, Flat Head, Pends Oreilles, Wallawallah and Bannack Indians. Of navigational importance to the western immigrants are the three buttes located in the Lava Plains of Idaho. Among his discoveries, Bonneville is credited with finding the Humboldt and San Joaquin Rivers.
