Bumping Lake and its surrounding wilderness define this high-elevation landscape within the Snoqualmie National Forest. The geography is dominated by a complex network of glacial and volcanic peaks, including Mt Aix and Bismarck Peak, which rise above drainages such as Deep Cr and Granite Cr. The southern portion of the map reveals the historical site of Copper City, reflecting the area's legacy of prospecting and resource extraction. Significant ridgelines like American Ridge and Miners Ridge separate alpine lakes such as Lily Lake and Root Lake from the Bumping River valley. This 2014 survey documents the rugged infrastructure of the Nat For Dev Rd 1800 and its role in providing access to the deep mountain basins and high timberline regions of central Washington.
