ALASKA VOLCANO OBSERVATORY
Monday, June 28, 2004 03:00 PM ADT (23:00 UTC)
58°39' 51.2" N, 137° 9' 50.41" W Glacier Bay National Park and Preserve,
Last week, AVO received several reports and photographs of small
"ash" clouds and possible thermal activity on the east face of Mt. Crillon
in the Fairweather Range in Glacier Bay National Park and Preserve. The
phenomenon observed are the result of small but persistent slope failures
and dry, dusty rock avalanches on the upper part of Mt. Crillon coinciding
with a period of warmer than usual air temperatures. The dust clouds,
although resembling volcanic ash, are not the result of any kind of
volcanic activity Mt. Crillon is not a volcanic peak and no known volcanic
features are located nearby.
