2016 Map of Mount Hayes B-4 NW

About this map

The Alaska Pipeline and Richardson Highway parallel the Delta River through this high-altitude corridor of the Alaska Range. The map documents a critical infrastructure bottleneck where engineering feats must contend with the glacial landscape, including the proximity of the Black Rapids Glacier to the north and numerous high-energy drainages. A series of steeply graded tributaries, such as Suzy Q Cr, Boulder Cr, and Whistler Cr, descend from the surrounding peaks toward the river valley. The eastern edge of the quadrangle is defined by the rugged ascent toward higher summits, with deep incisions from Trims Creek and Castner Creek carving through the mountain massif. This topographical study captures the modern industrial footprint of the Trans-Alaska Pipeline System as it navigates one of the state's most formidable interior mountain passes.
