You would likely get some argument from OTHERS about that:
Roughly 26,000 years ago, the glaciers of the Northern Hemisphere had reached their maximum size before beginning to melt — a point that scientists call the Last Glacial Maximum (LGM). At the LGM, the Earth’s ocean levels were at their lowest point and extensive reaches of dry land were exposed along the continents’ coasts.
I happened to run across something I wasn't aware of(not the first time) concerning exploration of North America's continental shelf. Dr. Adovasio(of Medowcraft fame) has been systematically SURVEYING AND SAMPLING OFF WESTERN FLORIDA since 2008. His mission -- primarily to find evidence of human occupation during the last ice age. There of course have been "accidental" discoveries on our continental shelf going back decades but he(amongst others maybe?) has apparently been able to acquire the necessary resources to do some serious exploration.
Not much but, the LATEST. BTW, don't do any "News" searches about his work. You'll find absolutely NOTHING.
Extent is easiest to measure. Weight is the most difficult ~ until we get the ground penetrating radar down tight and then we can figure that out by measuring acceleration at depth ~ dirt and rocks move aside due to the weight of the ice.
I've only seen one good one so far and that was the use of ground penetrating radar combined with other methods to take a look at the tectonic plates sitting on top the plume that provides the heat for the magma that fires up Yellowstone. Geology had that one within the last year I believe ~ kept it near the family throne room to make sure I could read it all.
Let's say Maximum ice is not all that PrecICE.
Which brings up something else ~ the archeology shows two thrusts ~ which makes sense ~ if you have Maximum Ice and giant ice flows are putting out to see you might not be able to cross the Atlantic. Both before that time and after that time you should be able to do that ~ particularly if you are adapted to eat vast amounts of seal meat.
