About this map

The Porcupine River carves a winding path through the southeastern corner of this landscape, serving as the dominant hydrological feature of this remote subarctic region. Flowing through the Yukon-Koyukuk Census Area, the river is a historic corridor for navigation and subsistence in the Alaskan interior. To the west, the drainage of Fish Cr moves across the undulating terrain, defining the local watershed patterns within the townships of t28n r24e and t27n r24e. The map illustrates the characteristic topographic transition from the river valley's low-lying areas to the higher elevations in the north and west, providing a precise look at the land's contours before these waters join larger systems downstream.
