A note about Mt. Adams: Mt Adams is a volcano! It is the second highest peak in Washington, too; and larger than Mt Rainier in sheer eruptive volume. It would bury Manhattan Island in over 300 feet of material (Darryl Lloyd). At 12,286 feet, is also the 3rd highest volcano in the Cascade Range, after Mt Rainier and Mt Shasta!
Learn more about the geology, history, and sights of this mountain in this book by Darryl Lloyd, I can’t recommend it enough. I have a signed copy: www.mtadamsbook.com/
I took a few timelapses at this meadow, and elsewhere, for the Equestria: Into the Wild film, too.
