Photographs showing the impact of the 1964 Alaska tsunami at Cannon Beach (courtesy of the Cannon Beach Historical Society). (A) Oblique aerial photograph of the lower Elk Creek valley (now Ecola Creek) that flows through downtown Cannon Beach. Decking from the old Elk Creek bridge was torn from its abutments and transported 300 m upstream. A foundation in the lower part of the photo marks the original postition of a house that was carried 400 m upstream and deposited between the bridge sections. (B) View to the northwest across Elk Creek showing bridge pilings and piers, all that remain after the tsunami destroyed the Elk Creek bridge in 1964. Bell Harbor Motel can be seen in the distance across the creek. (C) The Bell Harbor Motel suffered considerable damage from flooding during the tsunami, including broken windows, water damage and destruction caused by drift logs. The roof of a different building was left in the front yard of the Motel after being carried several hundred yards by the waves. (D) View to the southeast looking across Elk Creek at the bridge remains and house transported hundreds of meter inland by the tsunami. Figure is from Witter (2008).
