1962 Map of Harrison Bay B-1

About this map

Colville River Delta dominates this coastal survey, where the massive river system fractures into a complex network of braids and distributaries. The landscape is defined by the heavy presence of the Kupiqruak Channel and the Colville River, which carve through the tundra before emptying into the shallow waters of Harrison Bay. Amidst the shifting currents lies Anachlik Island, a prominent landmass within the delta's intricate reach. This 1950s-era photogrammetric compilation by the Army Map Service captures the stark, water-saturated geography of the North Slope, revealing a terrain of endless thermokarst lakes and ponded water typical of the Arctic coastal plain. Precise elevation markers, such as Vabm 10 and Vabm 19, provide the only vertical landmarks across this low-lying expanse of the Beaufort Sea coast.
