2019 Map of Holy Cross C-2 SE

About this map

The Innoko River winds through this interior Alaskan landscape, defining the character of the terrain within the Yukon-Koyukuk Census Area. This region is marked by a complex network of wetlands and seasonal watercourses, where the river’s path creates a dynamic environment of oxbow lakes and meandering channels. The eastern portion of the sheet rises toward higher ground, contrasting with the river valley’s low-lying drainage patterns. Detailed surveying by the U.S. Geological Survey reveals the intricate relationship between the waterway and the surrounding topography, offering a clear view of the land's natural contours before the influence of modern infrastructure or settlement. The map serves as a primary record of the hydrological layout in this part of Alaska as it existed in 2019.
