Multnomah Falls, on the Columbia River Highway in Oregon. The photo postcard was by (Arthur) Cross and (Edward) Dimmitt.<br><br><p>This postcard was with my grandparents' travel papers. Either of them could have traveled from Seattle as a child, or after they were married and before they left for Boston in 1941.<br><br></p>
