Description

First state of the Thomas Cowperthwait edition of this map and the first to show Utah and New Mexico Territories. The map was first issued by SA Mitchell in 1846, showing Oregon & Upper California. In 1849, the Gold Regions were colored in, but the map remained largely unchanged. With the sale of Mitchell's business to Thomas Cowperthwait in 1850 a new edition of this map was produced. This 1850 state is the only state not to show counties in Oregon and California. The map shows many Indian Tribes, Forts, mountains, rivers and a few early trading houses. Several of the major routes through the west are also illustrated. Pre-Gadsden purchase border with Mexico. No sign of Lake Tahoe. The Gold Region of California is noted, but not colored. An interesting early map of the west, one of the first to appear in an American Commercial Atlas.
