Alaska Earthquake March 27, 1964. Fissures in Seward Highway near The Alaska Railroad station at Portage, at the head of Turnagain Arm. Many bridges were also damaged. At some places, tectonic subsidence and consolidation of alluvial materials dropped both highway and railroad below high-tide levels. Photo by U.S. Army.
