2018 Map of Ketchikan D-2 NE

About this map

The glacial ice and steep drainage basins of the Tongass National Forest dominate this 2018 survey. The landscape is defined by the massive Through Glacier in the northern portion of the quadrangle, which feeds into the intricate hydrology of the S Fork Chickamin River to the south. This remote terrain marks the high-altitude boundary line between the Prince of Wales-Hyder Census Area and the Ketchikan Gateway Borough. The map illustrates the shifting state of Alaskan ice fields in the early twenty-first century, providing a precise record of glacial margins and meltwater paths through the coastal mountains of the Unorganized Borough. Researchers can trace the complex network of unnamed peaks and ridges that separate these major hydrologic features.
