Hogback Ridge is a glaciated mountain ridge located in the Chugach Mountains, in the U.S. state of Alaska. This landform is situated east of Valdez, west of Thompson Pass, and the Richardson Highway traverses the southern base of the mountain. This feature takes its name from the Hogback Glacier on its northern slopes, and in turn the glacier was named in 1898 by Captain William R. Abercrombie. Abercrombie led an 1898 expedition seeking a route from coastal Alaska to the Klondike. Precipitation runoff and meltwater from the mountain's glaciers drains into tributaries of the Lowe River, which in turn empties to Prince William Sound. The famous Horsetail Falls, which is located in Keystone Canyon, receives its source from the south slope of the mountain.
