yeah. All of these parks are amazing in their own respects. Along those lines, the movie they showed at the visitor center at Mt. St. Helens (i *think* the most recent volcano to go off in the states, Hawaii aside) really freaked me out. It ends with the statement "... because it's only a matter of time!" And then the curtains open and your staring (thru a glass wall) into the open crater of this massive volcano. The effect was super cool... but it had me ready to get off that volcano... and fast! The power of nature to transform the landscape. Amazing. The earth is indeed very much alive.
