2020 Map of Black A-1 SW

USGS Topo · Published 2020

About this map

The low-lying wetlands of the Kusilvak Census Area are defined by an intricate network of water and tundra drainage in this 2020 survey. Melatolik Creek meanders through the northern reaches of the quadrangle, while the southern landscape is shaped by the presence of the Ear River. This remote Alaskan terrain is characterized by a dense concentration of small lakes and ponds, indicating a highly saturated environment typical of the Yukon-Kuskokwim Delta region. The map meticulously records the township and range boundaries, including t23n r88w and t24n r87w, which provide a formal grid over a landscape otherwise dictated by the shifting paths of its waterways.
