1958 Map of McGrath A-3

USGS Topo · Published 1964

About this map

The Middle Fork Kuskokwim River snakes through this Alaskan landscape, defining a complex drainage system within the Seward Meridian. This 1958 field-annotated survey reveals a wilderness shaped by the Trimokish Hills and the convergence of several major waterways. The Windy Fork Middle Fork Kuskokwim River and the Big Fork River cut deep valleys between high ridges, illustrating the primary drainage patterns of the Kuskokwim Basin. With no roads or trails recorded, the map emphasizes the natural geography, showing the North Fork and the intricate glacial and alluvial features common to this interior region. It captures the area as it was mapped by photogrammetric methods in the mid-1950s, serving as a foundational record of the topography before later changes in the territory.
