Hello Marcus - Under optimal atmospheric viewing conditions, Redoubt often has a steam plume visible from Anchorage - this is the result of the still-cooling 2009 lava dome and fumaroles around the dome. These plumes are a frequent occurrence at Redoubt and, on their own, don't signify a change in activity. Yesterday's plumes caught a higher-than-usual level of attention.

It looks cloudy today, but you can view our Redoubt webcams here: https://www.avo.alaska.edu/webcam/Redoubt_-_Hut.php Hope this is helpful, Thank you, Cheryl Cameron -------- Marcus L Hartley wrote: Driving home on Anchorage Hillside last night around sunset, I saw a plume coming off of Redoubt. I took a photo, that shows the plume if zoomed in. Nothing on your site about activity at Redoubt. Are plumes not noteworthy? -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
