Lewis and Clark Trail Inventory: Oregon and Washington
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 states of Oregon and Washington. On October 10, 1805, the Lewis and Clark Expedition first arrived in Washington at the confluence of the Clearwater and Snake rivers. They continued down the Snake to the Columbia River, and then down the Columbia arriving at the Pacific Ocean in November. They entered—and in 1806 left—Oregon in the Wallula Gap of the Columbia River. They spent the winter near Astoria, Oregon and then headed home in late March 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.
