1951 Map of Mt. Katmai A-4

About this map

Katmai Pass serves as the central focal point of this 1951 aerial survey, marking a low-lying crossing between the dramatic peaks of Mt Cerberus and Mt Mageik. The map illustrates a highly active geological landscape within Katmai National Park, most notably the massive Mageik Landslide and the heights of Trident Volcano. The hydrology of the region is defined by the South-flowing Mageik Creek and Alagogshak Creek, both of which drain toward the wide Katmai River delta. As the river meets the Shelikof Strait, it forms a broad Tidal Flat before opening into Katmai Bay. The transition from glacial peaks like Topographers Peak to the coastal waters illustrates the dramatic elevation changes that characterize the Katmai Wilderness.
