Many historians consider Lemhi Pass the most important site along the Lewis and Clark National Historic Trail. It was here that the dream of the Northwest Passage died and the expedition began its passage through the Rocky Mountains with horses acquired from the Lemhi Shoshone. Stands of fir and pine trees and mountain meadows look much the same today. The Lewis and Clark Backcountry Byway ~ A memorial near the pass commemorates Sacajawea, the expedition's Shoshone interpreter.
"The gravesite of the left arm of General Stonewall Jackson - After General Jackson's arm was amputated nearby at the Wilderness Tavern, his doctor, Hunter McGuire didn't feel that it was appropriate for the General's arm to be buried in a mass grave with other amputated limbs, so he took the arm, and brought it to his family's home nearby and had it buried in the family plot."
The Lewis and Clark as widely known owes much of its success to the Native American wife of a French trapper named Sacagawea. Sacagawea not only led the explorers along a safe route now known as the Lewis and Clark Trail, but also helped the group to survive by protecting them from area Native American tribes. Sacagawea also provided translation services to explorers and Native Americans along the Lewis and Clark Trail.
