Lewis and Clark NHT Visitor Centers and Museums

This map shows a range of features associated with the Lewis and Clark National Historic Trail, which commemorates the 1803-1806 Lewis and Clark Expedition. The trail spans a large portion of the North American continent, from the Ohio River in Pittsburgh, Pennsylvania, to the mouth of the Columbia River in Oregon and Washington. The trail is comprised of the historic route of the Lewis and Clark Expedition, an auto tour route, high potential historic sites (shown in black), visitor centers (shown in orange), and pivotal places (shown in green). These features can be selected on the map to reveal additional information. Also shown is a base map displaying state boundaries, cities, rivers, and highways. The map conveys how a significant area of the North American continent was traversed by the Lewis and Clark Expedition and indicates the many places where visitors can learn about their journey and experience the landscape through which they traveled.

In the early 1800s, the Ohio River was relatively easy to navigate, with one major exception.  

Near modern-day Louisville, the limestone bedrock is exposed for one short section. The river falls twenty-six feet in 2.5 miles, enough to make a canoe descent tumultuous at high water and impossible at low water.106 In 1805, Josiah Espy described the falls viewed from Clarksville as a “zigzag channel which is only navigable at high water.” 

People who regularly traveled the busy Ohio River—whether French, American, Shawnee, Haudenosaunee, or Delaware—knew how to get around these rapids. They knew when the water was high enough to take a boat or canoe over them and when they needed to carry their vessels around the waterfalls (known as a portage).  

William Clark’s family had settled near these falls. Here he met up with Meriwether Lewis here to begin their transcontinental journey.

The falls no longer look like they once did. Private interests constructed a canal and locks south of the falls starting in 1825, to improve navigation on the river. The federal government later enlarged the canal and added additional dams, so that by 1964, dams made the river no longer navigable at this point: all traffic had to go through the canal.
