Mount Mageik (left) and Mount Martin (distant right) tower above the flat floor of the Valley of Ten Thousand Smokes. The deposits in the valley are pyroclastic flows that formed during the 1912 eruption of Novarupta, the largest eruption of the 20th century. Glacier-covered Mageik has a broad summit containing multiple cones and vents. Photo by Game McGimsey (U.S. Geological Survey, Alaska Volcano Observatory).
