About this map

Post River flows through the center of this wilderness area within the Yukon-Koyukuk Census Area, carving a path between significant elevations. To the east, the Terra Cotta Mountains rise sharply, flanked by the steep walls of Graptolite Canyon and the high elevations of Barren Ridge. This landscape is characterized by its isolation, with no recorded roads or human settlements, highlighting the remote nature of the Alaskan interior in the early 21st century. The drainage basin includes Post Lake in the southeast corner, which serves as a notable hydrologic feature in this mountainous terrain. The map provides a detailed view of the natural topography and township boundaries, such as t25n r24w and t24n r23w, documenting a portion of Alaska where the physical environment remains the primary focus of the survey.
