Bogs and Fens in the Hudson Bay Lowlands
Describes structural and vegetative features of bogs and fens in the peatlands area south and west of Hudson Bay, examined in summer 1957 mainly near the confluence of the Attawapiskat and Muketei Rivers (approx. 53 N, 86 W). Distinctive features of the ridge-shaped raised bogs are their undulating...
