1958 Map of McGrath B-3

About this map

Windy Fork Middle Fork Kuskokwim River defines the drainage patterns of this Alaskan interior landscape, where braided river channels and shifting sandbars dominate the valley floor. To the south, the Trimokish Hills rise sharply from the lowlands, providing a clear boundary between the flat riparian corridors and the more elevated, complex topography of the region. The map reflects a mid-century period when the Middle Fork Kuskokwim River and its various tributaries, such as Khuchaynik Creek, remained largely roadless and untouched by modern infrastructure. This 1958 field-annotated survey, based on aerial photography from the early to mid-1950s, offers a detailed look at the natural hydrology of the Yukon-Koyukuk region before any significant human development altered its character.
