Traveling down the Columbia River on November 4, 1805, the expedition passed a large Watlala village near here with more than 200 people and many canoes. They camped on the north shore, downstream from the village. The area was thick with waterfowl, and Clark noted that they had difficulty sleeping that night with the noise from swans, geese, ducks, and cranes.37

Waterfowl rely on specific habitat, food sources, and migration route conditions. Established in 1964, Ridgefield National Wildlife Refuge preserves pasture, marshes, floodplain forest, and oak woodlands to ensure habitat for waterfowl and other wetland wildlife. Anticipating increased flooding and higher temperatures due to climate change, the refuge is developing strategies to address these effects. These efforts include invasive species control, pasture management for migrating geese, and water control and rotation plans to increase seasonal wetlands productivity.38

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.
