1951 Map of Mount Katmai B-4

About this map

Valley of Ten Thousand Smokes dominates this section of Katmai National Monument, revealing a landscape profoundly reshaped by the massive 1912 eruption. The map serves as a record of the aftermath, detailing the ash-filled basin through which Knife Creek and the River flow. The presence of Novarupta and Mt Cerberus at the head of the valley illustrates the volcanic source of this terrain, while surrounding peaks like Mt Griggs and Mt Juhle define the high-altitude boundaries. Glacial activity is equally prominent, with the Knife Creek Glaciers feeding the drainage systems from the eastern heights. This 1951 photogrammetric survey, revised in the 1970s, provides an essential topographical study of these active geological features, including the Buttress Range and the silt-laden Ukak River as they appeared mid-century.
