Allan Peak and Mt. Ennis. The route described under Mt. Allan should be applied to Mt. Ennis, and, unless other information is forthcoming, Allan Peak is considered to be as yet unascended. Mt. Ennis has been ascended by two routes: (1) The probably identical routes followed by the Survey in 1906 and the Gardiner-Gest party of 1933. (2) The traverse to the Ennis-Vaux saddle as made by the A. C. C. parties in 1939.
