2018 Map of Coleen C-4 SW
USGS Topo · Published 2018About this map
Boulder Creek winds through the interior of the Yukon-Koyukuk Census Area, cutting across the southeastern and southwestern reaches of the landscape. The drainage system, which also includes the headwaters of Boulder Cr, shapes the topography within the Public Land Survey System divisions of t32n r21e, t32n r22e, t31n r21e, and t31n r22e. This area of interior Alaska is defined by a high-elevation drainage divide, where the relief rises above 1,800 feet near the eastern edge. The absence of roads or permanent structures in this 2018 survey emphasizes the isolation of the upper Boulder Creek basin, a territory primarily defined by its physical geography and the administrative boundaries of the National Geospatial Program.
