1951 Map of Mt Katmai

About this map

Katmai National Monument and the surrounding volcanic landscape define this 1951 survey, capturing a region profoundly altered by the 1912 eruption. The Valley of Ten Thousand Smokes stretches across the center, leading toward the jagged peaks of The Trident and Knife Peak. At the head of the valley, Novarupta marks the epicenter of one of the 20th century's most significant volcanic events. The map illustrates a transition from these ashen highlands to the deep waters of Naknek Lake and Grosvenor Lake.
