Douglas Volcano

Mount Douglas is a 2140m high andesitic stratovolcano located on the Alaskan Peninsula, 315km SW of Anchorage. No historical accounts of activity at Douglas exist. The most prominent feature of the heavily glacially eroded ediface is the deep crater containing an acidic lake in the summit region. Measurements taken in 1992, recorded a temperature of 21`C and a pH of 1 and noted an active fumarole field on the N flank of the crater. During an overflight in September 2007, no significant fumarolic activity could be seen and the lake was found to be frozen.
