Historical 3-D map of Astoria Canyon

Had Lewis and Clark made their expedition at a time of lower sea levels, their journey along the Columbia River could have take them to the edge of Astoria Canyon. However, their westward push stopped ten miles short at Fort Clatsop where the modern day mouth of the Columbia meets the Pacific Ocean. Image courtesy of Lewis and Clark 2001, NOAA/OER.
