Caption:Steam rising off of the roiling lake in the bottom of the south crater of Korovin. Although the walls are plastered with tephra, recent, rigorous phreatic activity has stripped the lower walls to bare rock.

Caption:Aerial view into the summit crater of Korovin. This level of fumarolic emission from the slightly oblong, 60–90 m (200–300 ft) diameter, sheer-walled orifice at the bottom of the crater is apparently fairly typical and can account for the periodic observations of plumes from Atka Village. At times, a shallow body of gray, turbid water partially fills the inner crater and, in 2004, was observed roiling. Phreatic explosions from this water-rich, high-temperature system may be responsible for the occasional localized ash-fall deposits seen on the upper flanks of Korovin. Photograph by R.G. McGimsey, AVO/USGS, July 19, 2004.

Caption:A view of the 2004 field camp location on the northeastern flank of Mount Cleveland just up the beach on the central isthmus from the western end of Applegate Cove. This same location was where the 2002 field camp was located for field operations. Three tents are observed to the left of the main (larger) weatherport tent.
