About this map

Cape Simpson reaches into the Beaufort Sea at the northern edge of this coastal survey, marking a prominent point on the Arctic shoreline. The landscape is defined by its transition from the open sea to a dense network of coastal wetlands and water bodies, including the significant Sinclair Lake in the northwest. In the southern portion of the quadrangle, the Piasuk River winds through the flat, saturated terrain, illustrating the complex drainage patterns typical of the North Slope. This region, governed by the Public Land Survey System divisions of t19n r11w, t19n r10w, and t18n r11w, represents a largely untouched maritime environment where the permafrost-influenced hydrology creates a mosaic of countless unnamed ponds and marshes around named features like the river and lakes.
