About this map

Chakachatna River winds through this expanse of the Kenai Peninsula, where a complex network of glacial meltwater and seasonal channels defines the landscape. The hydrography of the region is characterized by significant features like Middle River and the braided path of the McArthur River, which dominate the southern portion of the sheet. Further north, the Chuitkilnachna Cr and Nikolai Cr snake through low-lying areas, illustrating the intricate drainage patterns of this coastal region. The absence of roads or permanent structures on this U.S. Geological Survey sheet highlights the undeveloped nature of the terrain, where water features like the Noaukta Slough serve as the primary landmarks. This survey provides a precise record of these shifting waterways and the wetlands that lie between them, offering essential data for understanding the physical geography of this remote Alaskan district.
