The establishment of a new nation following the American Revolutionary War meant there were many ripe chances for explorers to investigate the new world that comprised the United States. ""Exploring North America 1800-1900, Revised Edition"" traces the history of the exploration of western North America and the impact it had on the histories of both the United States and Canada. These stories present an exciting and inspiring narrative, full of moments of great courage, insight, and individual and collective achievement. Coverage of this title includes: John Wesley Powell's summer expedition that traversed the length of the Colorado River through the Grand Canyon; the other explorers, aside from Lewis and Clark, who joined Thomas Jefferson's ambitious program of exploration, such as the Dunbar-Hunter Expedition and the Freeman-Custis Expedition; and, a look at the societies that resulted from the new Western territories, including Native Americans, Hispanics, and African Americans.
