Millions of people from the ends of the earth have put the Grand Canyon on their bucket list, so it might seem impossible to find solitude on the South Rim. Late fall through early spring, though, if you're willing to brave the cold temperatures on the high plateau above the endless chasms below, you just might find a quiet ledge of rim rock from which to watch day break.
Set your alarm and get here early; colors begin animating the sky well before the clock-time for sunrise. Don't underestimate the cold. Gloves and a thermos are indispensable as you face the east expectantly. And once the sun's rays begin pouring into the canyon, make sure to direct your gaze north and west: the naked geology comes alive with light, shadows dancing for a vertical mile below you.
(On this particular morning when I took this photo, a rare inversion caused a layer of fog to fill the Canyon; the sun rose over a sea of clouds--a once-in-a-decade-or-so event!)
