Petroglyphs at Columbia Hills

In October 1805, the Lewis and Clark Expedition camped by Horsethief Lake on their way to the Pacific Ocean. Today the site is perhaps best known for camping and the extraordinary display of Native petroglyphs that were saved from inundation by the John Day Dam. You can view several centuries-old petroglyphs from the parking lot, but for the really good stuff, you'll need to take one of the scheduled tours.
