National Geographic Student Expeditions selected my photograph from the Iceland expedition that I co-led in 2012 as the 2013 catalog cover photo. The photo was shot on Skaftafell Glacier in mid-July. We were on our way off the glacier, winding down a ridge. I was at the head of the group and when I turned around to check on everyone I saw the possibility of this photo. Fortunately the students got into the idea too and this is the result!
