Reply to comment by Additional_Data4659 in Made this little poster this evening because I was bored. Never been to Washington but I have passed through, y'all have a beautiful state! by lntercontinental

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.
