2019 Map of Iditarod C-3 NW

About this map

The Dishna River meanders through the northwest corner of this remote Alaskan interior, defining a landscape of complex hydrological drainage and high-elevation relief. The western reaches are dominated by the river's broad floodplains and oxbows, while the central and eastern sections are characterized by a network of steep-cut valleys and upland ridges. These drainages include the prominent Porcupine Creek and its southern tributary Guggenheim Cr, as well as the easterly Deadwood Cr. The survey illustrates the difficult topography of the Yukon-Koyukuk region, where small seasonal waterways like Saint Patrick Cr carve through the terrain. The lack of roads or structures emphasizes the wilderness character of the area, typical of the Iditarod mining district's hinterlands where development is restricted to the watercourses that once guided prospectors and surveyors.
