You've got to wonder how long it might have been since anyone set foot in some of these areas (if ever).
The glaciers just carve right through the mountains in many places. Even with the low contrast caused by the plane window, I found the glaciers a fascinating viewing experience.
In addition to the great whale viewing, we also had as great view of Mendenhall Glacier and the surrounding mountains from the deck of our excursion boat near Juneau.
