Boulder Creek winds through this interior Alaskan wilderness, cutting through the high elevation terrain of the Yukon-Koyukuk Census Area. This topographic survey captures the landscape as it appeared in 2018, emphasizing the natural drainage patterns and the remote character of the Brooks Range foothills. The map is defined by its significant relief, with contour lines illustrating the steep gradients and valleys that dictate the course of Boulder Creek as it flows across the southwestern sections. The Public Land Survey System (PLSS) grid lines for Township 32 North, Range 18 East and adjacent blocks provide the primary structural framework for this largely undeveloped expanse.
