Saskatchewan Glacier. During the summer of 1942, U. S. Army training and equipment-testing forces constructed a road from the Lake Louise-Jasper highway to the tongue of the Saskatchewan Glacier, thence up the glacier to the head of Cattleguard Valley. Using this route, motorized snow vehicles attained the Columbia Icefield and proceeded to the summit of The Snow Dome. An army climbing party, led by J. Riegelhuth, ascended Mt. Athabaska from the Saskatchewan Glacier by way of the S. rock slope.
