2017 Map of Holy Cross C-6 NW

About this map

East Fork Andreafsky River winds through the northern reaches of the Nulato Hills in this interior Alaskan landscape. This 2017 survey by the U.S. Geological Survey documents the intricate drainage patterns of the Kusilvak Census Area, illustrating how the river system carves through the undulating terrain of the upland country. The area is defined by its topographic complexity rather than human infrastructure, with the map focusing on the physical geography and public land surveying boundaries such as t31n r68w and t30n r67w. Researchers studying hydrologic shifts or the physical character of the Alaskan interior will find the detailed contouring of the river valley particularly valuable for understanding the natural movement of water through this unpopulated wilderness.
