On Good Friday of 1964, a disaster struck Southcentral Alaska. A 9.2 magnitude earthquake struck Alaska and seriously damaged or destroyed many Alaskan communities, either from the shaking or from the resulting tsunami.

PortageNearly destroyed in the 1964 quake, the old townsite of Portage was abandoned. The few remaining buildings, further damaged by time and the elements, are slowly disappearing among the new marshy growth of what was once dry ground. Trees that once grew here are now now a bunch of dead trunks, killed by the marsh that was created when the land sunk. |
