The Pacific-Alaska Navigation Company was an American passenger and freight ocean shipping company that operated between 1912 and 1916 on the West Coast of North America.
The company was operated by president H.F. "Bert" Alexander, a former Tacoma longshoreman who worked his way up the ranks.
The steamer SS Yukon ran aground June 23, 1913 on the northwest coast of Sanak Island on a reef subsequently named for the ship.
Both ships were operating in heavy fog within Puget Sound, 18 miles north of Seattle.
The Admiral Sampson sank, killing 11, while the Princess Victoria returned to Seattle with the survivors of the accident.
