On September 4th, 1940 Lynn V. Simmons was a part of a geological survey team working on Lamotte Peak at about 12, 700 ft when a storm hit at about 2 pm. Simmons and his three coworkers began head for spike camp, established on the head of boundary peak. Simmons lagged behind the others. He was last seen as he came down the saddle of Lamotte peak on a long, rocky ridge to Bald Ridge (about half a mile from the peak). His coworkers waved to him and he waved back. He was never seen again. Several storms in the following days/weeks dropped 6 to 8 inches snow and hindered search efforts.
