1985 Map of Lookout Ridge B-2

USGS Topo · Published 1985

About this map

National Petroleum Reserve in Alaska dominates this 1985 survey, illustrating a massive expanse of the North Slope defined by its complex drainage systems rather than human settlement. The Titaluk River and Kigalik River meander across the terrain, accompanied by smaller watercourses like Quartzite Creek and Birthday Creek. This landscape represents a mid-1970s aerial survey period when the federal government was actively mapping the petroleum reserve's interior. One of the few markers of human transit is a solitary Tractor Trail cutting through the center of the sheet, providing a rare terrestrial connection across the tundra. The southern portion of the map is punctuated by Birthday Pass, a significant landform situated near the headwaters of the regional creek systems, highlighting the area's isolation and reliance on natural geographic corridors for navigation.
