2013 Map of Umiat D-4 NW

About this map

Glacial thermokarst lakes and intricate wetland complexes dominate this remote Arctic terrain within the North Slope Borough. Located in the northern reaches of the state, the landscape is defined by the Public Land Survey System boundaries of T 8 N T 7 N and T 7 N T 6 N, marking the transition between township grids. The surface is a dense mosaic of thaw lakes and ponds, typical of the permafrost-underlain coastal plain, where drainage patterns are often indistinct and dictated by subtle topographical variations. This survey provides a precise look at the hydrology and land divisions between R 2 W R 1 W as they existed in the early twenty-first century.
