About this map

The Colville River dominates this mid-1950s Arctic landscape, winding through a complex system of braided channels and sandbars. Along its eastern bank, the Itkillik River converges into the main flow amidst a dense network of tundra ponds and lakes. To the south, the prominent Ulukshak Bluff stands over the river valley, marking a significant change in the local elevation.

A marked Winter Trail cuts across the western plateau, indicating the seasonal transportation routes vital for navigating this terrain before permanent road infrastructure. The western half of the map is also defined by the boundary of the Naval Petroleum Reserve No 4, reflecting the era's focus on national energy security and resource exploration. Several smaller water bodies, including the Kogosukruk River, Ingalunt Creek, and Kikak Creek, drain the uplands into the Colville basin.
