Upper Unalaska Valley

Sixty years later, only one intact cabana can be seen from the road in Upper Unalaska Valley. So me buildings were moved into town for housing after the war, and others salvaged for lumber. Many were emoved during an environmental cleanup. The rest have fallen due to years of rain, wind, and snow load. Although the buildings in Upper Unalaska Valley are no longer standing, many of the foundations remain; a drive through the valley provides a sense of what it might have been like to live here during World War II.

Mile 5.3 - Water System Remnants
On the creek bank at the washout are traces of the original World War II water system. The rectangular concrete structure on the left was the chlorination station. Protruding from the bank to the right of the station are wood-stave water pipes wrapped with wire.

Mile 5.3 - Munitions Magazines (1942-1943)
When you reach the washout at the end of the road, look to your left across the river. The two black tunnel-like openings in the hillside are the entrances to munitions magazines known as elephant steel shelters or Armco huts. These structures were built of panels of heavy-gauge corrugated steel bolted together and covered with soil. Grass and willow soon grew over the soil, making the shelters very difficult to detect.

Unalaska Valley/Pyramid Valley Water System (1943)
Soon after the Fort Mears troops moved to Unalaska Valley in July 1942, testing revealed that the water supply for the new garrisons was contaminated. The source of the contamination was traced to living quarters located above the watershed. Although personnel quarters were immediately moved down the hillside below the watershed, by the end of the year it became necessary to strictly ration water use. During this time, an “outbreak of acute gastro-enteritis was traced to unclean messing gear due to a shortage of available hot water … in the galleys” (War Diary: Dutch Harbor, Alaska).

As soon as the snow melted in Pyramid Valley the following spring, work began on a new water system. Water from Pyramid Creek was channeled through 16- inch-diameter wood-stave and cast-iron pipe at Icy Creek Dam. From here, waterlines ran to Amaknak Island and to two dams in Upper Unalaska Valley. Water flowed from these dams downhill to the chlorination facility (Mile 5.3) before reaching Garrisons 2 and 5.

When completed, the new water system provided a fresh water supply of approximately 3,500,000 gallons per day to all the military installations on Amaknak and Unalaska islands. This water system served the City of Unalaska for many years after the war. Remnants of wood-stave pipe can still be seen in Unalaska and Pyramid valleys and on the shore of Unalaska Bay.
