Close but not perfect comparison of photos of Pavlof Volcano from 1928 (top) and 2005 (bottom)showing change in the summit morphology. The 1928 image is a scan of a photo from Thomas Jaggar's expedition article in National Geographic Magazine (January 1929 volume, article entitled 'Mapping the Home of the Great Brown Bear'). The 2005 image is by Chris Waythomas.
