Check it out! (Sorry, now I broke the location-specific link because the borrowed GPS unit was returned to its owner.)
If you click on the "terrain" button you can see the lava flows and the crater of the volcano.
(That's right, for you non-locals, Mt. St. Helens is a volcano. Fortunately, it hasn't
been active erupted in the past couple years.)
I wish I was with them!
