Notes

Abstract:
The Attawapiskat River has cut through 30 m of mid-Silurian limestone ∼90 km west of James Bay in the Hudson Bay Lowland. Limestone cliffs of 12–15 m provide local relief along the river but inland the terrain is flat, covered by 1.5 m or more of peat. The area emerged from the Tyrrell Sea ∼4400 yr. B.P. Since that time two karst hydrogeological zones have become established. These are: (1) a vadose fluvio-karst zone in the exposed limestone along the river represented by disappearing lakes and streams; and (2) an organo-karst zone represented by sinkholes on or next to limestone bioherms within the peat mantle. They occupy 16% and 13% of the study area, respectively.
