About this map

The Snoqualmie National Forest defines this high-elevation landscape in King County, dominated by the hydrology of the western Cascades. This 2017 survey details a critical water resource area, notably the Green River Watershed and the northern reach of the Howard A Hanson Reservoir. The terrain is shaped by significant peaks like Cougar Mountain and Mt Lindsay, with drainage flowing through a complex network of creeks such as Eagle Cr and Lindsay Cr.

Transport through this protected wilderness is restricted to a dense network of forest roads, including NFD 5100 RD and NFD 5470 RD, which navigate the steep contours between Chester Morse Lake and the Rex River. For the researcher, the map preserves the mid-20th-century infrastructure of the National Forest System, documenting the precise placement of forest development roads and the drainage patterns of the N Fork Green River before modern environmental shifts.
