About this map

The vast Colville River Delta dominates this mid-century topographic record of Alaska’s North Slope, where a complex network of channels and distributaries meets the Beaufort Sea. The intricate hydrology of the region is documented through the winding courses of the Kupigruak River and the braided Colville River, which separate to form Anachlik Island and Nuekshat Island. This survey, based on 1955 aerial photography, illustrates a landscape characterized by thousands of small thermokarst lakes and tundra ponds spread across the coastal plain.

Notable landmarks like Pikonik Mound and Nimrod provide vertical relief in an otherwise low-lying environment. Tributaries such as the Miluveach River, Kalubik Creek, and the Kachemach River drain into the southern reaches of Harrison Bay. The map is a vital resource for understanding the baseline geography of this Arctic region before extensive industrial exploration altered the surface features of the North Slope.
