The sheet was anchored in the [[Coast Mountains]] of [[British Columbia]] and [[Alberta]], south into the [[Cascade Range]] of [[Washington (state)|Washington]]. That is one and a half times the water held in the [[Antarctic]]. Anchored in the mountain backbone of the west coast, the ice sheet dissipated north of the [[Alaska Range]] where the air was too dry to form glaciers.<ref name=Hill2006/>
It is believed that the Cordilleran ice melted rapidly, in less than 4000 years. The water created numerous [[Proglacial lakes]] along the margins such as [[Lake Missoula]], often leading to catastrophic floods as with the [[Missoula Floods]]. Much of the topography of [[Eastern Washington]] and northern [[Montana]] and [[North Dakota]] was affected.<ref name=Hill2006/>
