About this map

Umiat serves as a focal point for this mid-century survey of the North Slope, situated where the Colville River bends through a landscape of distinctive river bluffs and drainage systems. This area is characterized by the intersection of several major arctic waterways, including the Anaktuvuk River, Chandler River, and Itkillik River, which cut through the National Petroleum Reserve in Alaska. The presence of the Umiat Gas Field and the Umiat Field reflects the mid-20th-century exploration for natural resources in the region.

Industrial and survey efforts are marked by the Umiat Principal Meridian and the east-west Base Line. Notable landmarks such as Umiat Mountain and the Niakogon Buttes rise above the surrounding tundra, while the Winter Trail provides a glimpse into the seasonal transport routes required in this environment. The map also captures numerous bluffs along the riverbanks, such as Shivugak Bluff and Tattitgak Bluff, documenting the erosion and geomorphology of the Colville valley.
