1958 Map of Lime Hills B-1

About this map

Glacial action and high-altitude water systems define this interior Alaskan landscape, dominated by the sweeping course of the Chilligan River. This 1950s survey, compiled from aerial photography, illustrates a complex alpine environment where the Necons River and Igitna River carve through steep terrain. The presence of numerous crevasses across the higher elevations indicates the active glacial nature of the region during this period. With no roads or trails recorded, the map reflects a purely natural state of the Alaskan wilderness, focusing on the hydraulic patterns and topographical relief of the Lime Hills region. This document serves as a baseline for understanding the drainage and ice formations of this area before later environmental shifts.
