From the record
“The Rock Fort Campsite is a natural fortification on the south shore of the Columbia River in The Dalles, Oregon, United States. The Lewis and Clark Expedition camped at this defensible spot for three nights in late October 1805, just after it passed Celilo Falls on its descent to the Pacific Ocean, and again for one night on their return journey.”
