Summary
[edit]
| Description |
English: Sunlight from the south leaves north-facing slopes in shadow. Away from the lake’s sapphire-hued waters, the land appears as a combination of grey, brown, and green. Vegetation lines the slopes at lower elevations, but much of the land in this image lies above the tree-line. Treeless slopes rise above Lake Minnewanka in the north and the south. The off-white lake shores suggest that the lake was not completely full when ALI acquired this image. The Bow Valley has been shaped by a combination of rivers and glaciers. Sediments from the ancestral Bow River appear below glacial sediments. Beginning 25,000 years ago, the Bow Valley glacier ground through the valley. That glacier was later overtaken by a continental glacier. Besides the Bow Valley, occupied by Lake Minnewanka, evidence of glaciation in this image also appears to the south, in the amphitheatre-shaped cirque. |
