Just south of the southeastern caldera rim looking west across the southern caldera wall of Fisher volcano. AVO scientist Dr. Jim Gardner investigates an older basaltic lava flow. The low area on the right is the southern caldera floor, and the snow-free peak on the right is one of the stratocones partially destroyed in the caldera-forming eruption 9,400 years ago. The snow covered peaks in the background are Westdahl (left) and Faris Peak.
