1951 Map of Mount Katmai D-1

About this map

Kamishak River dominates this mid-century topographic record, winding through a glacial landscape defined by deep valleys and sharp relief. The mapping, derived from 1951 aerial photography, captures the intricate braided channels and gravel bars where the Kamishak River meets its major tributaries. To the west, the long valley of Strike Creek cuts a linear path through the high terrain, while the South Fork drains the eastern slopes. The contour work, completed by the Geological Survey, illustrates the stark verticality of the peaks surrounding these water systems, providing a clear picture of the hydrological patterns before any modern development or major environmental shifts in this part of the Alaska Peninsula.
