The False Pass, Alaska Cannery was located on the north side of Unimack Island at False Pass. You can look across False Pass to the south end of the Alaska Peninsula.
False Pass (Wikipedia), is aptly named as the west end opens up in a wide and inviting waterway that is shallow with a twisty and obscured channel. In 1972 the channel was not marked and local knowledge was needed to transit west of the cannery.
The Cannery was built in 1919 by the P.E. Harris, Co. and burned down in the spring of 1981 when a bearing failed in a generator and the rotor dropped down onto the stator while the generator continued to run producing a jet of flames out the bottom of the generator that set the oil soaked creosote floor of the powerhouse on fire.
Here are a few Pictures of the False Pass Cannery Buildings.
