About this map

Katmai National Monument dominates this mid-century topographic study, showcasing a landscape shaped by significant volcanic and glacial activity. The northern section is defined by the braided channels of Angle Creek, while the towering Martin Mountain rises in the northeast, its slopes marked by intricate glacial Crevasses. The map details the transition from high mountain passes to valley floor drainage systems, providing a clear view of the hydrological relationship between high-altitude peaks and the lower-lying river basins.

Kejulik River flows through the southern half of the quadrangle, joined by tributaries such as Gas Creek and Takayoto Creek. A critical transit point for those navigating this interior terrain is identified at Kejulik Pass. This 1951 aerial survey captures the area before the modern era of expanded park infrastructure, noting the National Monument Boundary (Approximate) as it existed during the early years of Alaskan statehood preparation.
