Mt. Owen. 1940, E. Cromwell, Miss G. Engelhard. Probably the first ascent via N. ridge and traverse. From Lake O’Hara via trail over McArthur Pass into valley of McArthur Creek to old campsite at 5000 ft.; 2 h. Thence up E. face (grass slopes, gullies and scree) to N. ridge at timberline. Follow long ridge throughout (pinnacles and rotten rock) to summit glacier cap, where the N. E. snow slope is followed to E. ridge and few hundred feet below the summit. This would be time-consuming if ice were bare. Ascent 6.5 h. from Lake O’Hara. Descent by easy broken rock of S. ridge and S. E. face. Total time from Lake O’Hara 12 h.
