Hohoho, no it's not. That's Mt. Lassen, by jiminey. Oh boy.

Lassen Volcanic National Park. Shield volcano, dome volcano, cinder volcano....volcano, volcano, volcano. VILFs. All sorts of volcanoes. They're all here.
Mt. Lassen is the worlds biggest plug dome volcano. Plug dome. I'll show you plug dome.

I believe that is a chunk of dacite that I'm sitting on. Old stuff, whatever it is.
See that contrail in the sky? That's close to the height of Mt. Everest . Good God Allmighty, I don't know how people do it. There are some disastrous attempts, though. Jon Krakuaer is a bad-ass writer. You better believe it.
