1970 Map of Bettles A-1

USGS Topo · Published 1977

About this map

Ray River meanders across the southern landscape of this northern Alaskan interior survey, which captures a critical moment of industrial infrastructure expansion in the 1970s. The most striking feature is the corridor for The Trans-Alaska Pipeline (Under Construction), slicing through the terrain alongside an established Winter Trail. These paths represent the evolving transportation and energy network of the region, contrasting with the primitive Cabin located near the riverbank. To the east, the Fort Hamlin Hills dominate the topography, providing a stark geographic boundary. This edition includes purple-ink revisions compiled from 1975 aerial photography, offering a multi-year perspective on the early stages of pipeline development before its completion.
