Abstract
Aerial and ground observations of the peatlands of southeastern Labrador reveal shallow circular lakes that apparently formed by the coalescence of fen pools and small lake basins through the degradation of intervening peat deposits. Geomorphic evidence suggests that lake development proceeds through three stages: initial deepening and enlargement of pools through peat decomposition, shoreline stabilization by ice-ramparts, and formation of compound lakes through the fusion of adjacent basins. This process is not dependent on permafrost, which is absent from the region. The water chemistry of these peatland lakes is very similar to that found in nearly bedrock-controlled basins except that total phosphorus, iron, and apparent color are significantly higher in the former.
