Aerial view of 80-m (260 ft)-high Novarupta, a blocky rhyolite lava dome that marks
the vent for the 1912 eruption that created the Valley of Ten Thousand Smokes in Katmai
National Park and Preserve, Alaska. This eruption was the most voluminous on Earth in the 20th century, ejecting nearly 30 cubic kilometers (7 cubic miles) of material in 60 hours. Falling Mountain, a lava dome truncated by the 1912 eruption, is visible behind the Novarupta dome; snow-capped Mount Mageik volcano can be seen at top of the photograph. Photograph by T. Miller, U.S. Geological Survey, June, 1979.
