Sand & Gravel Deposits along the Assiniboine Spillway


Assiniboine Spillway Sand and Gravel DepositsThe results of glacial drainage, both englacial (Arrow Hills Esker) and proglacial (Assiniboine Spillway) are clearly visible on the DEM. The esker is approximately 15 metres in height and composed of coarse shale gravel. The spillway is 70 metres deep and mostly erosional. The Assiniboine flats, an anomolous area of deposition within the spillway is an area which is very actively mined for sand and gravel.
