2020 Map of Harrison Bay A-2 SW

About this map

The Colville River dominates this Arctic landscape on the North Slope, where the massive waterway splits into braided channels and expansive wetlands. This 2020 survey illustrates the dynamic hydrology of the region, where the primary river system meets the Itkillik River in a vast delta-like environment. The terrain is defined by a dense network of seasonal ponds and tundra lakes, reflecting the seasonal shifts and water distribution characteristic of this northern territory. Surveyed by the U.S. Geological Survey, the map documents the Colville River as it traverses through the northern reaches of the t9n r4e and t9n r5e townships. The lack of permanent infrastructure or settlements underscores the seasonal and environmental focus of this survey, capturing a specific moment in the shifting Alaskan hydrography.
