I subscribe to this channel so I'll preface this with the warning that this is not a video but a short talk illustrated with stills. None of the images you see (except the Google Earth shots) are of the Hannegan volcano because it happened 3.5m years ago (I guess that's "recent" for geologists). The author has a library of images he uses to illustrate what he's saying. But AFAIK the geology seems well-informed and the slides are typical of what it might have looked like. Mainly, it's another example of how complicated the geology of Washington State is.
