1955 Map of Umiat B-4

USGS Topo · Published 1970

About this map

The Colville River carves a massive path through the Arctic landscape on this 1955 survey, where the remote settlement of Umiat stands as a vital outpost within the Naval Petroleum Reserve No 4. This area represents a mid-century frontier for energy exploration and logistical support, evidenced by the infrastructure of Docks and a Beacon near Umiat Lake. The topography is dominated by dramatic riverine features like Umiat Mountain and the steep slopes of Shivugak Bluff and Tattitgak Bluff which overlook the braided channels. Overland travel in this era relied on specialized routes, with several stretches of Winter Trail and Tractor Trail marked across the tundra to connect the settlement with its surrounding watershed, including Bearpaw Creek and Seabee Creek. The map reflects a period of intense federal interest in the North Slope's petroleum potential before major commercial developments transformed the region.
