Doc’s picture here was like a 2×4 to my forehead:
A zillion years ago, I was accustomed to flying USAF tankers from Sacramento to Fairbanks, Alaska, for a couple of weeks of weird weather and flying. On the way and back, we flew over the Brooks Range, where the serious peaks barely rose above the snows that filled the spaces between them:
As a hiker, I knew that it would take a full day to hike between peaks just like these in the Sierras, but only a couple of hours on snowshoes and minutes on a snowmobile.
The Brooks Range is, for some reason, a picture I will carry in my head forever. Thanks, Doc!
