Abstract
Theories about cirque development have postulated accelerated freeze-thaw weathering and erosion around and beneath semipermanent snow patches and small glaciers. I studied the Dome Glacier in the Canadian Rocky Mountains. Results indicate freeze-thaw temperature conditions in the presence of moisture on rock surfaces above the glacier randkluft throughout the spring or early ablation season. Freeze-thaw regimes are restricted to the randkluft lip area in early to mid-summer. With the widening of the randkluft in late summer and early autumn a freeze-thaw regime is driven by local atmospheric frost alternations. The randkluft environment, while cool and damp, appears not to provide a special freeze-thaw environment under these conditions. Nonetheless, over the course of the observation period, significant parts of the glacier margin were exposed to accentuated freeze-thaw temperature regimes which may be a factor in rock weathering and cirque development
