Keystone Canyon is located 12 miles east of Valdez. The Richardson Highway follows the Lowe River through the heart of the canyon from beginning to end.
Keystone Canyon is an impressive narrow canyon with walls over 600ft tall. It is just wide enough for the Richardson Highway and Lowe River to sit side by side edge to edge. The Lowe is only about 30ft at its widest in the canyon.
Naming: Keystone Canyon was named in 1898 by Captain William R. Abercrombie, USA, presumably after Pennsylvania, the Keystone State.
