About this map

Kocacho Cr and Marten Cr flow through this interior reach of the Yukon-Koyukuk Census Area, defining the drainage patterns of a landscape marked by substantial elevation changes. The territory is divided by the rectangular grid of the Public Land Survey System, encompassing portions of t31n r8e, t31n r9e, t30n r8e, and t30n r9e. This 2018 survey illustrates a region defined by its natural watercourses and topographic relief rather than human settlement, as no roads or structures are recorded on the sheet. The proximity of these two creeks suggests a divide where small tributaries begin their descent through the surrounding uplands, providing a precise look at the hydrology of this specific northern Alaskan township block.
