Within these mountain ranges are countless glaciers, streams, and lakes. The beauty of Alaska’s mountains is renowned the world over, as are the mountaineering opportunities. The vast majority of Alaska’s mountains remain unclimbed. Difficult access and costly airplane flights keep many mountaineers away, but those who venture into Alaska’s mountains can find abundant rewards.
