Washington Park station serves a few attractions: the zoo, the Rose Garden, the Japanese Garden, the World Forestry Center, and other locations. It’s the deepest subway station in North America, and one of the deepest in the world overall. But even cooler: The entire station is inspired by science – mainly geology.
Along both platforms (in each direction) is a platform-length core sample, taken during construction, and above and below it are little science tidbits or illustrations.
(That’s a platform full of plant biologists, returning from a conference party at the World Forestry Center.)
The elevator only stops at two levels, but while you’re inside you can see how far above sea level you are. (I found a video someone took of the elevator in action, where you can see it more clearly)
Difficult to see, but the elevator floor indicator says “16 million years ago” and “the present”.
I have a Flickr album with a few other photos from this station, and if you’re curious what else I did in Portland, there’s also an album taken mostly above ground!
