It's just half the mountain it was when I was a kid -- and that's what's so fascinating about it. Unless you're a member of the X-generation or Y-generation, you remember how it lost half of the mountain in a huge explosion in 1980 -- the most significant event in recorded history (this link has a fascinating tale of the event). In the foreground, the two travelers do what people do every day -- stop to take a shot to remember it by.
Here's a full view inside the crater. You can click in the image and move side to side to spin around 360.
The drive up to the mountain is a wonderful history and biology lesson in itself. If you haven't already done so, put it on you life's list to make the visit to Mt. St. Helens.
