Holocene gelifluction in a snow‐patch environment at the Forest‐Tundra Transition along the eastern Hudson Bay Coast, Canada
The Holocene chronology of gelifluction events in a snow‐patch environment of the Richmond Gulf area, eastern Hudson Bay Coast (northern Québec), has been constructed using sixty radiocarbon‐dated buried organic horizons. The samples were recovered from nine soil trenches located along an altitudina...

The Holocene chronology of gelifluction events in a snow‐patch environment of the Richmond Gulf area, eastern Hudson Bay Coast (northern Québec), has been constructed using sixty radiocarbon‐dated buried organic horizons. The samples were recovered from nine soil trenches located along an altitudinal gradient associated with a chronosequence as determined by the regional land emersion curve. The most significant gelifluction activity occurred after c. 2,800 B. P. Gelifluction events occurred around 5,600, 5,000, 4,500, 3,150, 2,500, 1,550, 1,200 and 450 B.P., and at present. According to the frequency of 14 C dates. gelifluction has been particularly active between 2,800‐2,300, 1,700–900 and 600‐300 B.P., and at present.
