Nice work. I've lived here all my life and had no idea there were this many active volcanoes to worry about.

All of the cascades were at one point active volcanoes! When you have an oceanic tectonic plate subducting under a continental tectonic plate then you will get a volcanic mountain range. Washington State is geologically very interesting!

Nick Zentner from the university in Ellensburg has a facinating series of videos on youtube about the geology of the PNW. 10/10 highly recommend.

I actually learned this from his course at CWU! Excellent professor and everyone interested should watch his courses/series. If I had taken that class at the beginning of college I might have become a geology major.

I'm from the East Coast and the tallest mountains are barely a hill compared to what we got here. It's cause they're "retired".

Never knew til I moved out here!

The Appalachian mountain range is significantly older than the cascades, and have since eroded down to the "hills" we see today
