A collage of photographs taken in the Canadian Rockies: a moraine lake and valley of the Ten Peaks and a climber approaching the summit of Mt. Athabaska. John Norman Collie, a chemist and mountaineer who lived from 1859 to 1942, climbed extensively in Skye, the English Lake District, Ireland, the Alps, Norway, and the Himalaya. On three expeditions to Canada, he carried out extensive mapping and is credited with the discovery of the great Columbia ice field. Collie's contributions to chemistry are featured in an article on pages 41-47. The images were provided by chemist and mountaineer Robert Rittenhouse.
The cover was designed by Betsy True.
