From the Plains to the Pacific
Between May 1804 and September 1806, 31 men, one woman, and a baby traveled from the plains of the Midwest to the shores of the Pacific Ocean. They called themselves the Corps of Discovery. In their search for a water route to the Pacific Ocean, they opened a window into the west for the young United States.
