Three American climbers lay in the dark, sharing a custom-made sleeping bag on a portable ledge dangling from a massive cliff high in the Himalayas. They were anchored to the north face of Mount Jannu, one of the world’s biggest, sheerest rock walls. “I know we still have a lot to do,” Alan Rousseau said to his two fellow climbers. “But I feel like we just did something cool.”The next day, Rousseau, Matt Cornell and Jackson Marvell — little known outside of climbing circles, for the moment — stood at Jannu’s summit. Before them were the white tips of other major peaks, including Everest and Kangchenjunga.
