Sacajawea and the Corps of Discovery (Lewis & Clark Expedition) traveled down the Columbia in 1805, and back up it in 1806. But I am combining the sites for both ways as one trip west down the Columbia River to the Pacific Ocean: the Washington side, and the Oregon side.

An illustrated timeline and exhibits about the Corps of Discovery, and a few other displays pertinent to the area. Click on the photos below to enlarge them. Navigate through them by clicking arrows forward and backward. Note: Lewis & Clark didn't name Cape Disappointment, shipboard explorers before them did.
I've been in a wheelchair for 30+ years. It poses some challenges for traveling. Maybe others can benefit from my experiences.
