1971 Map of Philip Smith Mountains B-5

USGS Topo · Published 1973

About this map

Galbraith Lake and the surrounding tundra of the North Slope are documented here in the early 1970s, a period when the region was seeing increased industrial activity related to northern resource development. The presence of Galbraith Camp, a Landing Strip, and a Borrow Pit alongside a Winter Road suggests the establishment of staging grounds for pipeline or infrastructure projects. The landscape is dominated by the massive Oolah Valley and the winding course of the Itkillik River, which receives the Itikmalak River and Itkillik Creek. To the east, the Atigun River flows through the mountain passes. The map's detailed topography, based on 1970 aerial photography, reveals the complex glacial and fluvial patterns of the Brooks Range foothills, including the isolation of Itkillik Lake.
