1971 Map of Chandalar B-6

USGS Topo · Published 1977

About this map

The Trans-Alaska Pipeline cuts a straight path through the northwest corner of this subarctic landscape, reflecting a transformative moment in Alaskan infrastructure. Surveyed just as the energy corridor was being established, the map documents the Middle Fork Koyukuk River valley and its surrounding drainage systems. Low-lying flats in the southeast give way to the prominent Poss Mountain and a network of named waterways like Minnie Creek and Marion Creek.
