Hi Sue - The UAF Geophysical Institute gives tours every Wednesday during the summer. AVO's facilities are included in that tour (we don't have enough staff to run our own tours). Best wishes on your travels, Cheryl -------- Sue Easterling wrote: Is the observatory open to the public? What days and times may I visit? I will be starting a Nat Geo tour on 24 Aug in Fairbanks. I would very much like to visit. Thanks. -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
