2019 Map of McGrath A-1 SW

USGS Topo · Published 2019

About this map

The Terra Cotta Mountains dominate this high-altitude landscape in the interior of Alaska, where the northern foothills of the Alaska Range rise sharply from the valley floor. Running north-to-south through the eastern portion of the sheet, the South Fork Kuskokwim River serves as the primary hydrological artery, its braided channels carving through the glacial terrain. This 2019 survey documents a vast area devoid of roads or permanent settlements, instead highlighting the administrative divide between the Yukon-Koyukuk Census Area and the Bethel Census Area. The contour density illustrates the dramatic verticality of the peaks, providing a clear visualization of the natural barriers that have historically dictated travel and drainage patterns in this corner of the state.
