2018 Map of Black River B-5 SW

About this map

Tchulkade Lake sits near the northern boundary of this high-latitude terrain, centered within a landscape defined by intricate drainage patterns and expansive wetlands. The eastern portion of the sheet is marked by the meandering path of the Little Black River, which winds through the Public Land Survey System boundaries of t18n r21e and t17n r21e. This 2018 survey documents a remote interior Alaskan environment where the hydrography is the primary defining characteristic of the land. With no roads or established settlements noted on the map, the cartography focuses on the elevation contours and the network of small lakes and seasonal water bodies that feed into the larger river system, providing a precise record of the regional hydrology as it existed in the early 21st century.
