Chilkat Oil Company Refinery Site

The Chilkat Oil Company Refinery Site is a historic industrial site near the ghost town of Katalla, Alaska. It is located at the head of Katalla Slough, an arm of Katalla Bay, and about 20 mi southeast of the mouth of the Copper River. The site consists of the ruined remnants of Alaska's first petroleum refinery, which operated from roughly 1911 until 1933, when it was partially destroyed by fire and abandoned. Oil had been discovered in Katalla Bay as early as 1902, and the company was formed to exploit the resource, reportedly producing more than 50,000 gallons of gasoline in 1921. Facilities at the site included a warehouse, tank house, running house, coal house, condensing house, and residence, all of which were reported to be in ruins in 1972.

The site was listed on the National Register of Historic Places in 1974.
