Crepuscular Rays in front of Cahas Mountain on the Blue Ridge Parkway, VA
Crepuscular Rays or "God Beams" at sunset near Appistoki Peak and Lower Two Medicine Lake, Glacier National Park, 2012.

The certain knowledge that there was potential for a spectacular sunset helped me keep going as I struggled up a hill with my camera and tripod.  I got set up just in time to capture some remarkable sunbeams cutting through the valley in front of Appistoki Peak.  It was worth the climb!
