Photo Gallery


Compound, 2161-m-high Snowy Mountain volcano lies 15 km NE of Mount Katmai. An ice-topped Holocene lava dome on the central skyline partly fills an ice-mantled amphitheater that formed as a result of edifice collapse of the NE slope of the NE Snowy edifice. The true summit (Peak 7090) lies just behind the dome to its right. The Serpent Tongue glacier spills from the amphitheater. No historical eruptive activity has been documented, but fumarolic activity has been observed at NE Snowy, along with a zone of shallow seismicity.
