Corps of Discovery

High Point of the Journey

"thus far I had accomplished one of those great objects on which my mind has been unalterably fixed for many years.," wrote Meriwether Lewis, 456 days after setting out from St. Louis.

Lewis, George Drouillard, Hugh McNeal, and John Shields crossed the Continental Divide here on August 12, 1805, in advance of the main expedition. They left the headwaters of the Missouri and entered the upper Columbia River Basin.
At 7,373 ft. (2,247 m.) Lemhi Pass is the highest elevation on the westward route of Lewis and Clark.

"Portage Hill"


Lewis and Clark hoped to find a practical land route - a portage - between the Missouri and Columbia Rivers. Optimistically, they called this place "Portage Hill." Later, after five weeks of arduous travel through the rugged Rocky Mountains they learned this was not the Northwest Passage they sought.

At the Edge of an Empire


The Louisiana Purchase

Today you stand at the border of two states. In 1805, it was the boundary between two nations.
Purchase of the Louisiana Territory from France in 1803 strengthened the United States' drive to span the North American continent.
British and U.S. interests
were racing to occupy the Pacific Northwest, wanting control of the valuable trade routes and commerce in the region. Both countries failed to fully acknowledge the sovereignty of resident Indian nations.
