1955 Map of Umiat D-2

About this map

The Itkillik River winds through this expanse of the North Slope, forming a complex network of tight oxbows and abandoned channels across a landscape dominated by thaw lakes and saturated wetlands. Photogrammetric methods from 1955 aerial photography reveal a wilderness where drainage patterns are constantly shifting, leaving behind a series of elongated pools and marshes. In the southwestern portion of the sheet, the Winter Road provides a seasonal transit route through the tundra, likely established to support early geological exploration or local movement when the ground is frozen. This remote corridor serves as a rare human imprint on an otherwise water-logged terrain, marking the intersection of resource interest and the challenging arctic environment during the mid-century era.
