Katmai, Alaska (#1)

photo of Katmai, Alaska

Katmai National Park, Alaska. The great 1912 eruption of Novarupta Volcano covered the flanks of Katmai Volcano with thick ash falls still visible in this photo taken from a light plane 51 years later. The summit of Katmai collapsed into a caldera (off to the right side) as magma was removed from beneath the peak. Trident volcano (center) was erupting a lava dome and andesite flow.
