2016 Map of Survey Pass B-1 SE

About this map

Gates of the Arctic National Park encompasses the majority of this quadrangle, preserving a vast expanse of the Brooks Range where the landscape is defined by high ridgelines and the headwaters of the Iniakuk River. The terrain here is dominated by steep contour intervals that descend toward the winding path of the river in the southern and western portions of the sheet. This 2016 edition illustrates the protected wilderness character of the Yukon-Koyukuk region, where the lack of human infrastructure or named settlements highlights the area's isolation. The Iniakuk River serves as the primary hydrological feature, cutting through the mountainous topography of t23n r25e and t21n r25e. This map provides a modern topographic record of the park's interior, useful for understanding the drainage patterns and elevation profiles of the northern Alaskan interior.
