Lewis and Clark Trail Inventory: Idaho
Signs, Statues, and Markers
By Kristopher K. TownsendUS National Park Service (LCNHT)
This page is an inventory of sites commemorating the Lewis and Clark journey in the present state of Idaho. In 1805, the Lewis and Clark Expedition entered what is now Idaho via Lemhi Pass. They headed north along the Lemhi River leaving the state above Salmon, Idaho. They returned to Idaho at the summit of Lolo Pass, crossed the Bitterroots via the Lolo Trail, and then canoed down the Clearwater and Snake Rivers. They returned much the same way in 1806.
In 2009, Lewis and Clark National Historic Trail of the U.S. National Park Service conducted an inventory of Lewis and Clark-related interpretive panels, signs, markers, and some statuary. The results of that survey have been compiled into a database and presented here by Kris Townsend. For other regions, see Lewis and Clark Trail Inventory. If you have more current photos and new sites to include, please contact editor@trailresearch.org and we will update this inventory.
