Unquestionably the leading American female alpinist of her time, Miriam O-Brien Underhill and her husband, Robert, brought modern mountaineering techniques to the Sawtooths in 1934 and 1935. In the process, the couple made many first ascents and wrote the first mountaineering articles on the range. You can read about her Idaho exploits on pages 17 and 18 of Idaho A Climbing Guide.
