1952 Map of Circle D-3

About this map

The Crazy Mountains and the Little Crazy Mountains dominate this high-latitude landscape, where the drainage systems of the Yukon-Koyukuk region are meticulously documented through aerial photogrammetry. Central to this map is the meandering course of Preacher Creek, which weaves through a wide, swampy valley floor. This intricate water network is further defined by tributaries such as Discovery Creek, Rock Creek, and Minto Creek. The survey, based on 1951 aerial photography and 1952 field annotations, reveals a wilderness devoid of roads or permanent settlements at the time of mapping. This absence of infrastructure highlights the topographic isolation of the era, offering a baseline for geologists and researchers studying the natural drainage patterns and landforms of the Alaska interior before later development or environmental shifts.
