2017 Map of Holy Cross B-4 NW

About this map

Bonasila River and its intricate meander loops define this unpopulated stretch of the Yukon-Koyukuk Census Area in west-central Alaska. The terrain transition is sharp, as the flat, water-logged lowlands of the river valley meet the rising slopes of unnamed ridges to the west. These hills, documented within Township 27 North, Range 63 West, reach elevations that overlook the drainage basins of the Stuyahok River and the Hawk River in the north. This 2017 survey illustrates a landscape of complex hydrology where oxbow lakes and abandoned channels reflect the shifting nature of the local waterways over time. Without roads or settlements, the map focuses on the natural topography and the legal boundaries of the Public Land Survey System, providing a baseline for environmental study or navigation in the Alaskan interior.
