About this map

The Knik Glacier dominates this landscape where the Municipality of Anchorage meets the Matanuska-Susitna Borough. This survey captures the massive ice fields and braided water systems of the region in the late twentieth century, showing the complex drainage from the Gannett Glacier and Colony Glacier into Inner Lake George. The terrain is characterized by steep glacial valleys and high ridges, with notable features like Grasshopper Valley and Low Ridge providing context for the area's geological structure.

While largely a wilderness study, the map identifies a solitary Landing Strip near the Knik River, indicating the importance of air travel for accessing this remote terrain. Numerous Crevasses are marked across the glacier surfaces, offering a detailed record of the ice conditions as they existed during the 1994 imagery update. Smaller drainages such as Paradise Creek and Fourth of July Creek add fine-grained detail to the watershed analysis.
