2019 Map of McGrath B-4 NE

About this map

Middle Fork Kuskokwim River snakes through this remote interior landscape within the Yukon-Koyukuk region. The terrain transition is marked by the sharp contrast between the river's meandering lowland course in the east and the significant elevation gains toward the northwest corner of the quadrangle. This 2019 survey, produced by the U.S. Geological Survey, meticulously details the topographic contours and hydrography across several townships, including t28n r30w and t27n r29w. While the area is devoid of named settlements or roads, the map provides a precise record of the natural drainage patterns and wilderness land divisions near the Kuskokwim's middle fork at the start of the twenty-first century.
