Hello Sally - Yes, whenever we visit our field sites, we clean the lenses (or rather, the plastic window of the webcam's housing). -Cheryl -------- Sally Latimer wrote: Beautiful day on Cook Inlet - spectacular view of Iliamna. Except picture covered with mass of dirty smudges. Please send somebody to the store for a bottle of Windex and clean winter off the lens. Thank You, Senior Citizen who enjoys viewing Alaskan Volcanoes and whose "home volcano" is Mount Lassen in Northern California. -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
