Novarupta Dome, upper Valley of Ten Thousand Smokes, Katmai National Park and Preserve, Alaska. The 380-m-wide rhyolite lava dome marks the center of the vent of the great eruption of 1912, and formed in the weeks to months following the June 6-9 explosive eruption. The vent itself is roughly 2 km wide and was backfilled by welded ash-flow tuff and fallback ejecta during the eruption. Photo taken during 20 August 2010 gas flight.

Oblique aerial view of the vent for the Novarupta eruption of 1912. The entire vent, which is about 2 km across, takes up much of the image; the smaller Novarupta dome sits in the middle of the vent and formed in the months after the great eruption that occurred June 6-9, 1912. The mound to the upper left of the dome, the "Turtle", is an accumulation of coarse debris that formed during the eruption.

View of the Valley of Ten Thousand Smokes, looking downvalley to the northwest. Whiskey Ridge in the foreground is composed of Jurassic-aged sedimentary rock of the Naknek Formation. Broken and Baked Mountains, also Naknek Formation, can be seen in the middle of the valley in the right mid-ground. Knife Creek cuts the thick ash-flow sheet of the valley floor as it drains the debris-laden Knife glaciers that cover Mount Katmai's northwest flank, in the foreground.

View of the upper Valley of Ten Thousand Smokes, looking west. The prominent feature in the foreground is Whiskey Ridge, composed of Jurassic-aged sedimentary rocks of the Naknek Formation. Two domes in the middle-right are Falling Mountain and Cerberus. Baked and Broken Mountains are visible on the right. In the basin in the center, the vent for the great eruption of 1912 is located, though Novarupta dome is not visible.
