1955 Map of Harrison Bay A-3

About this map

The Colville River meanders across the North Slope in this mid-century survey, defining the southern boundary of the National Petroleum Reserve in Alaska. The landscape is dominated by a complex network of thermokarst lakes and braided watercourses, including the Ublutuoch River and Fish Creek. A solitary Winter Trail cuts across the tundra in the northern portion of the quadrangle, illustrating the seasonal nature of travel and transport in this Arctic environment before permanent infrastructure. Geologic and navigational landmarks such as the Bluff and Big Bend provide orientation along the river corridor, while Ocean Point stands as a notable geographic reference point in an otherwise shifting terrain of water and permafrost.
