2020 Map of Harrison Bay A-3 SW

About this map

Colville River and the Ublutuoch River dominate this segment of the Arctic coastal plain in the North Slope Borough. This 2020 digital survey illustrates a landscape of complex hydrography, where the broad, meandering channel of the Colville River is flanked by an intricate network of thaw lakes and ponds typical of the permafrost-underlain tundra. The map provides precise modern documentation of the river's path and the surrounding wetlands before the potential shifts of a changing climate. Lacking named settlements or roads, the data focuses on the pure hydrological and geographical structure of the region, including the township and range divisions such as t9n r1e, t9n r2e, and t8n r3e.
