1954 Map of McGrath C-3

About this map

The Iditarod Trail cuts across this interior Alaskan landscape, following the northeast-southwest orientation of the regional terrain during the mid-1950s. This historic route is supplemented by a secondary Winter Trail, providing a clear look at the early overland transportation network before modern development. The drainage system is dominated by the Middle Fork Kuskokwim River, which is joined by the Windy Fork Middle Fork Kuskokwim River in a broad, braided channel typical of glacial runoff zones. Further north and east, smaller tributaries including Sullivan Creek, Sheep Creek, Bear Creek, and Khuchaynik Creek create an intricate web of watercourses that defined travel and subsistence patterns in this part of the Yukon-Koyukuk region.
