Great map of the one of the most important emigrant routes. South Pass in the central Rocky Mountains was the most important gateway to California and to the Oregon Territory. It was largely unknown until 1824 when the Crow Indians told Jedidah Smith and a party of trappers of this route south of the Wind River Mts. of Wyoming. Tens of thousands of emigrants crossed through the pass in route to their Western destinations. Salt Lake City is shown, as well as several smaller Mormon settlements in the region.
