An aerial view from the east shows Mount Griggs in the foreground with the distal end of the Valley of Ten Thousand Smokes (VTTS) ash-flow deposit in the distance, forming the flat, light-colored valley floor at the upper left. The VTTS ash flow was erupted in 1912 from Novarupta volcano; it traveled 21 km to the location shown in this photo. Griggs volcano is the highest of a group of volcanoes in the Katmai area. Three concentric craters are breached to the SW, the largest of which was formed by edifice collapse during the early Holocene.
