Mount Hood, Oregon: October 18, 1805

When towering Mt. Hood came into view, Lewis and Clark were able to place themselves on a map for the first time since leaving North Dakota. Over a decade earlier, the British navigator George Vancouver had mapped the coast of the Pacific Northwest, including the landmark of Mt. Hood. At this point the members of the Corps of Discovery were able to estimate with considerable accuracy their proximity to the Pacific Ocean.
