Fort Clatsop—Pacific Northwest Tribes and Climate Change

When they reached the Pacific Coast, the expedition members built Fort Clatsop on the Netul River, south of the Columbia, and spent the winter of 1805–1806 there. They did not enjoy the winter weather, complaining of the near constant rain, wind, and fog. As on their journey westward, they relied on the local Indigenous peoples, trading with them for food, woven mats, and useful waterproof hats. The locals were shrewd bargainers who had already been trading with Europeans along the coast for a decade. The goods that came in on European ships moved through Indigenous trading networks throughout the Pacific Northwest.41

Today, using similar networks and interconnections, many Indigenous nations in the Pacific Northwest work together to tackle the impacts of climate change. The PNW Tribal Climate Change Network is one of many cooperating organizations. Fifty-seven different Tribal governments make up the Affiliated Tribes of Northwest Indians. The Northwest Indian Fisheries Commission involves twenty separate groups. Members of these organizations are sharing knowledge and coordinating efforts to address the same kinds of climate change issues seen at many sites along the Lewis and Clark Historic Trail: warmer air and water temperatures, drought, decreased streamflow, changing wetlands, increasing wildfires, rising sea levels, stronger storms, and more. Declining populations of fish and shellfish, loss of harvesting areas, shifting bird and game migration routes, and decreased plant productivity are some specific impacts that affect Indigenous peoples.42

Many of these Indigenous groups have taken actions to adapt to changing conditions and enhance ecosystem resilience. These actions include river restoration and floodplain protection projects, wetlands improvement, forest management and carbon sequestration, and energy efficiency efforts. While each Indigenous nation is unique, they all have historical and contemporary relationships with Pacific Northwest ecosystems and are working to protect them for the future.43

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.
