We went on a cruise to Alaska last week. I've visited (and lived in) a lot of different states and countries in my life but never Alaska. I learned a lot. For one, I never knew it was a rainforest.
But I also saw something that really struck me. Below is a picture I took of the Mendenhall Glacier while in the visitors center. Notice the sign at the bottom and see how far it is from the glacier. If I'd visited there in 1935, standing at the spot, I'd have touched the glacier.
That's how far it's receded.
