Tongass National Forest dominates this Alaskan landscape, where the high-altitude terrain of the Ketchikan Gateway Borough is defined by glacial drainages and steep coastal mountains. The northern reaches of the map are carved by the Wilson River, while the central and southern valleys are shaped by the winding course of the Blossom River. Near the southeastern corner, the headwaters of the Keta River emerge from the high ridges. This 2018 survey illustrates the complex hydrography of the region, showing how these river systems navigate the deep glacial valleys before eventually reaching the coastal inlets beyond this quadrangle's boundaries.
