Navigation of the river is tricky, since it is swift flowing with multiple channels and many hazards, including debris loads, log jams and sweepers (trees hanging just above the water which "sweep" the surface as it flows by) that change position with each spring's ice breakup cycle.

The primary point of historic interest in Moose Factory was St. Thomas' Anglican Church, its beaded altar cloths made of moosehide and its wooden floor plugged with holes that can be opened when spring floods caused by the ice breakup threaten to sweep the church from its foundations - as happened on one occasion.
