Portage

Dead trees Crumbled house rooftop Collapsed garage Collapsed garage Crumbling house Rusted truck

Nearly 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.
