About this map

Gates of the Arctic National Park encompasses this expansive Brooks Range landscape, where the North Fork Koyukuk River carves a central valley between high-altitude terrain. The topography is defined by prominent peaks such as Boreal Mtn and the jagged Frigid Crags, marking the transition into one of the most protected wilderness areas in the United States. Tributaries including Kachwona Cr, Fishless Cr, and Pyramid Cr drain the surrounding mountains, reflecting a classic glacial-carved drainage pattern. This 2017 survey shows the river’s braided path through the valley floor, an essential corridor for seasonal travel and environmental study within the park's boundaries.
