Ross’ Hole—Indigenous Nations Address Climate Change in the Intermountain West

After struggling through deep snow in the Bitterroot Mountains, the expedition finally made it to this valley, later called Ross’ Hole, where they received food and assistance from some Salish people camped there.

On September 4, 1805, hungry and cold expedition members struggled down the north slope of the Bitterroot Mountains from Lost Trail Divide into an open valley, later named Ross’ Hole. Some 400 Salish people were camped in the valley, on their way to hunt bison with the same Shoshone people Lewis and Clark had just left. Offering a warm welcome, the Salish fed the explorers and traded gifts and goods with them.28

Part of the expedition’s purpose was for Lewis and Clark to be the United States’ ambassadors to the Indigenous nations they met along the way. To ease diplomatic relations, the expedition brought gifts, including several types of peace medals to bestow upon Tribal leaders. Although they were trying to project authority, the explorers relied on help from many Indigenous groups, such as the Shoshone, Nez Perce, and Salish, to survive and to succeed in their mission.29

Many of the groups Lewis and Clark met with still exist as sovereign nations. As part of their governing responsibilities, they are trying to protect their people and resources from the effects of climate change. The Upper Snake River Tribes Foundation (which includes the Shoshone) has recognized many impacts of climate change, including drying sagebrush steppe habitat, longer wildfire seasons, low summer river flows, higher water temperatures, and degraded rangelands. The Nez Perce have developed a climate change adaptation plan that includes carbon capture, natural resource inventories, and forest health and stream flow monitoring. The Confederated Salish and Kootenai Tribes have developed a Climate Change Strategic Plan. This plan includes gathering ecological knowledge from Tribal elders that, in their oral tradition society, reaches back 250 years or more. It addresses issues with air quality, forestry, fish, infrastructure, lands, people, water, and wildlife.30

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.
