Along with tragedy, a war can also bring innovation, as we’ve seen before. Set against a backdrop typically reserved for postcards, the decaying bunkers of the Aleutian Islands Campaign serve to memorialize a little-known chapter of WWII lore. Beginning in 1941, the US Army constructed over 100 buildings to secure the Dutch Harbor Naval Operating Base. Included are the bunkers and observation posts featured here, most of which are situated at Ulakta Head on Mount Ballyhoo. At 897 feat above sea level, these installations remain the highest coastal defense stations built in the United States.
