And the Laurentide ice sheet was a mile thick from where I type (upper Midwest) forming the Great Lakes only 12,000 years ago. The global warmists don’t tell you that however.
We bought a house in North Idaho about seven years ago and we were buried under a mile of the Cordilleran ice sheet.
Moral of my story: If you don't want to get buried under a mile of ice, don't buy a house near me.
I was just looking at Idaho State University's page on the Palouse and glacial Lake Missoula and learned a few new things:
In the Pleistocene ice age, vast ice caps covered much of North America and Eurasia; As much as a third of Earth's land surface was periodically covered in ice during this time. Four major glacial periods are recognized in North America: the Nebraskan, Kansan, Illinoisan, and Wisconsinan glaciations. Minor fluctuations occurred within each period.
Interglacial periods were periodically warmer than the present climate. Major interglacial periods include the Aftonian, Yarmouth, and Sangamon periods. The formation of glacial Lake Missoula occurred during the Pinedale (Wisconsinan) Glaciation.
