1951 Map of Mount Katmai B-4

About this map

Katmai National Monument defines this mid-century topographic survey, illustrating a landscape of immense volcanic activity and glacial movement. The sheet centers on the legendary Valley of Ten Thousand Smokes, where the braided waters of Knife Creek flow past Lethe. This area reflects the dramatic geology of the early twentieth-century eruption, featuring prominent peaks such as Knife Peak Volcano, Novarupta Volcano, and Falling Mountain. To the north, the Buttress Range and Mt Ikagluik tower over the Ukak River and its tributary, Ikagluik Creek. The map provides a detailed look at The Knife Creek Glaciers descending from high elevations, offering a study of ice and ash in one of Alaska’s most volatile regions. Notable landmarks like Baked Mountain and Broken Mountain are also mapped near Mt Cerberus.
