[Detail] The Grand Canyon. Clarence E. Dutton, 1882.

5) Westward Expansion

The mid-1800s saw a boom of map production as Americans and arriving immigrants moved west. Miners were unearthing gold. The Mexican War ended adding Texas, California, and land in what is now southern Arizona and New Mexico to the United States. Railroad lines were being constructed.

Use the Geographic Location map to browse maps of Yellowstone and the Grand Canyon created in this era. The maps will provide students an idea of what settlements existed. They can look for travel routes and discuss what frontiers people might have encountered.

For additional maps of this era, students can browse the Title Index of the map collection Railroad Maps, 1828-1900.
