"Shoshone" or Montana Territory
Intresting map of North America, with several interesting features.
Perhaps most noteworthy is the alternative name given for Montana Territory (Montana ou Shoshone).
The Gold Regions are named (Regon Aurifere) and the Mormon lands and New Jerusalem are shown. Arizona is shown below the Gila River. New Mexico is filled with Mines of Gold and Silver.
The map also tracks the route of the Transcontinental Railroad.
