2017 Map of Sagavanirktok B-3 NE

About this map

Ivishak River dominates this Arctic landscape, its braided channels carving a wide path through the wetland-rich terrain of the North Slope. This 2017 study by the U.S. Geological Survey captures the intricate hydrology of the region, where the river's broad floodplain meets the Echooka River in a complex system of seasonal watercourses and permafrost features. The map illustrates the vast, uninhabited character of the Alaskan wilderness, defined by the Public Land Survey System boundaries including t1n r15e, t1n r16e, and t2n r15e. For researchers of Arctic geography, the detailed elevation contours and hydrographic data provide a precise record of the river's course and the surrounding marshlands before the onset of further environmental shifts.
