Ah, the crazy things you remember from your college geology classes?!?!?!
The volcano in the photo is a lava flow, representing Mafic material. It is less viscous so it flows easier. Pacific Northwest material is Felsic. It has higher viscosity and so the eruptions are more explosive.
When Mount Hood erupts, many people will catch really, really big air.
Huck off and fly!!!
