I'm a little late on this, as it's been up since last month. But still, it was awesome to see.
For those who've watched the "National Parks - Our Best Idea" (or similar?) series, you'll love this. You might even hear Peter Coyote voicing over inside your head... or that John Muir scholar. ;-)
The AA print of Mt. Mckinley is breathtaking, and asking $55,000 IIRC.
All of the work is gorgeous, and many of them significant.
QT - you seem to be very involved in National parks work -- assume you've seen the Scott Nichols show?
