The team makes camp on a moraine on Edward Bailey Glacier en route to the formation known as Pool Wall. It's unclear exactly what the data collected during the expedition will reveal, but the glaciers in the area, compared with other parts of Greenland, showed little sign of melting. “This area," says Sevestre, "could be one of the last strongholds that hasn’t quite caught up with climate change just yet."

During down time at base camp, Honnold hangs from a fingerboard to strengthen his grip.

Honnold and Findlay discuss the route they plan to follow up the wall. “It’s so big," Honnold said, "you had to lie down to look at it. It seemed like it was going to be kind of too much.”
