Beacon Rock

Lewis and Clark passed Beacon Rock in 1905. The dense forest in this area is now more susceptible to fire due to increased drought and hot weather associated with climate change.

After making a difficult portage around the “Great Shute” rapids on November 2, 1805, the expedition continued downstream, noting the large basalt outcrop called Beacon Rock. Clark recorded that the river bottom and the mountains on each side of the river were thickly timbered with pine, spruce, cottonwood, and alder.35

Increased fire activity in the western United States is linked to climate change. Because heat and drought are more common now, stressed and dead vegetation provide more fuel for larger fires and a longer fire season. Drought and dry conditions in the summer of 2017 allowed the Eagle Creek fire to burn more than 48,000 acres along the south bank of the Columbia River, across from Beacon Rock. Scientific models project that the annual area burned in Oregon will increase by 200 percent in the future.36

Climate Change:Lewis and Clark Trail

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. 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.
