2016 Map of Mount Hayes B-1 SE

About this map

Robertson River dominates the drainage patterns across this interior Alaska wilderness, carving a significant valley floor through the mountainous terrain. Flowing primarily from the southwest toward the northeast, the river is fed by tributaries including Rumble Creek, which cuts through the central sections of the quadrangle. The map illustrates the complex hydrography typical of the region, where glacial runoff and seasonal melt create shifting channels and braided stream beds within the wider river corridor. This 2016 survey provides a precise record of these watercourses and the high-elevation topography surrounding them, detailing the steep contour changes that define the valley walls and the remote stretches of the Unorganized Borough.
