The Long Journey into Uncharted Lands
The journey of Lewis and Clark and the Corps of Discovery stands as one of the United States' great adventure tales, its fascinating history gripping our imagination as both children and adults. Many of us fantasize about what it must have been like to travel into uncharted territory, surviving on our wits, teamwork, and the help of people met along the way. The journey took Lewis and Clark through the present-day states of Missouri, Kansas, Iowa, South Dakota, and North Dakota, which had already been traveled and charted by white explorers. They then moved into the uncharted lands of Montana, Idaho, and Washington, culminating with a passage along the Columbia River to the Pacific Ocean.
