Late Pleistocene glaciolacustrine sediments, Ashcroft, BC.
This bluff along Thompson River just upstream of Aschroft exposes deformed silts and sands deposited in a glacial lake at the end of the
last glaciation about 11,000 years ago.  The folding is the result of melt of subjacent stagnant ice during deglaciation.  Exposures like
this provide information on the glacial history of the Canadian Cordillera.(photo by John Clague)
