Heavy snows are falling and will continue through Monday. Tuesday is calling for clearing skies and warming temps. I am in Phoenix for business and I am wondering if the South Rim would be accessible after 15 inches of new snow. Also wondering if anyone else is going up for this opportunity. I just purchased a Shen Hao 4x5 with a Rodenstock 210mm Sironar-N and can borrow a 75mm Schneider Super Angulon and am itching to pull the shutter. Wouldn't it be cool if my very first exposure taken with large format was a beautiful sunrise over the Grand Canyon on freshly fallen snow?
