PS10 is located at Pump Station #10 of the Trans-Alaska Pipeline System. This site is squeezed between the Richardson Highway and the Delta River, south of Black Rapids Lodge. Nestled in the narrow Delta River canyon in the Alaska Range, the station lies at the base of Devils Thumb peak. The Black Rapids and Castner glaciers fill nearby valleys. PS10 is part of a long-standing monitoring system for the pipeline. The Earthquake Center operates this system in conjunction with the Alyeska Pipeline Service Company.
