[pct-l] Cascades Volcano Observatory

[ATnavi@aol.com (ATnavi@aol.com)]

If you poke around, the Cascades Volcano Observatory page goes into the whole 
spiel on how they tie into the plate tectonics along the "Ring of Fire"... 
interesting reading! Remember, volcanoes can trigger quakes -- and 
vice-versa. :)

Great internal link for hikers:

Gives the background, eruptive history, and monitoring of all those special 
peaks along the PCT.
