About this map

The Copper River dominates this landscape, its braided channels weaving through a corridor of high glacial peaks and deep river valleys as they appeared in 1950. Along the eastern bank, an Old Railroad Grade traces the river's edge, serving as a physical reminder of the early 20th-century transportation routes through this corridor. This industrial footprint contrasts with the massive ice fields of the Schwan Glacier and Cleave Creek Glacier, which remain marked by dangerous Crevasses.

Regional drainage patterns are defined by the convergence of the Tasnuna River and the Tiekel River into the main Copper River channel. Distinctive landforms like The Peninsula and tributary valleys such as Thunder Creek and Jackson Creek highlight the geological complexity of the area. The map illustrates a transitional wilderness where the remnants of rail infrastructure meet the enduring presence of Alaskan glaciers and alpine streams.
