Preconsolidation of tills and intertill clays by glacial loading in southern Saskatchewan, Canada
Preconsolidation of pre-Battleford tills and intertill clays resulted in a narrow range of effective pressures (1800 ± 200 kPa) at 10 sites along a 1300 km transect across southern Saskatchewan. These data suggest an almost invariant loading system that is independent of total ice thickness, which r...
