1983 Map of Valdez A-6 SE
USGS Topo · Published 1983About this map
Keystone Canyon serves as a dramatic centerpiece on this 1983 survey, where the narrow passage forces a concentration of infrastructure and natural wonders. The Richardson Highway and the Trans-Alaska Pipeline both navigate this steep corridor alongside the braided channels of the Lowe River. This convergence highlights the late 20th-century engineering required to traverse the Alaskan interior, specifically showing the pipeline's path relative to established roadway and river routes.
