We’ve already looked at the Katmai/Novarupta eruption – the biggest one of the 20th century. This film was made before man made it to the Moon, and they apparently used it to show the astronauts how to interpret the landscape (wonder if Harrison Schmitt had anything to do with the training film’s making). (Yes, they did use their training on the Moon!)
This film shows some sweet details of the ash flow and the Novarupta dome and also has some detailed geology in it, although the Alaska Volcano Observatory, which posted it on YouTube, cautions:
Film produced in the late 1960s by the U.S. Geological Survey, in cooperation with the National Park Service, as part of astronaut training for Apollo missions. The geologic events discussed in this film reflect the state of knowledge in the 1960s — and is often quite different from today’s interpretations.
