Mountain close to Seattle

I took a trip with the 737 up to Boeing's Field close to Seattle to see what the airport looks like and practice some touch and goes.
But i got distracted when I saw this big mountain at the horizon. I took some screenshots of the trip.
This is actually a question ...

What is that thing? Is it St. Helen? The volcano I mean? ???
By the way I have tons more pictures and I took a movie of one of the touch and goes and it's all posted here
