1951 Map of Mount Katmai C-5

About this map

Katmai National Monument centers this mid-century survey, dominated by the massive landform of Mount La Gorce which rises between the northern and southern arms of the lake system. The landscape is defined by the complex aquatic connection between Lake Coville and Lake Grosvenor in the north, leading down toward the intricate Bay of Islands. This specific charting captures the region shortly after its expansion as a protected wilderness, showing the area as it existed in the early 1950s before more intensive modern recreational infrastructure. Human presence is notably sparse, marked only by a single Cabin near the portage area between the lakes. The intricate shoreline of the Naknek Lake (North Arm) and Naknek Lake (Iliuk Arm) provides a detailed look at the hydrology of the Alaska Peninsula during this era.
