Mt. Bosworth. The same party. Via S. E. face from motor road about 1 mile E. of Wapta camp. Up scree ledges and gullies; laborious but easy to bastion on E. ridge about 500 ft. below summit. Thence up steep cracks and rotten rock to summit (survey cairn). Ascent 3.5 h. The obvious route, presumably used by the survey, is via the shale ridge on the W. side, but at this time it was blocked by a snow cornice.
