Introduction
In southern and west central
Individual animals are too small to appear on all except very large-scale images. However, some animals (e.g. beaver) profoundly affect drainage systems.
5.24: Spring Fens West of Dancing Point, West Shore of Lake Winnipeg
The location is close to the junction of Ordovician and Silurian bedrock. Rocks of both periods include dolomite with argillaceous bands, and springs develop at the contacts. In the photo light-toned drainage way can be seen running from springs in the north 1 and centre 2. These are “spring fens”. They usually occur directly over springs in places where springs are widespread. The peat in spring fens varies in depth from shallow to deep but is thinner than peat in plateaus.[i] Wooded islands, probably covered by black spruce (Picea mariana), can be seen in the south 3, and the outline of a recent burn is in the lower left 4.
