Hi ddaveo, glad you're enjoying the thread, I think it really is a very important topic with regards to an EU model.
Any acceptable theory on the ice mass must accommodate itself to the geometry of the ice formation. There were several nodes on the Canadian Shield, from 15,000 to 17,000 feet in elevation, generally about 3 miles deep at these apexes. From these areas, the ice flowed outward in a radial pattern and in every direction, corrected only by coriolis forces or local topographical features. It flowed over hills hundreds and even over a thousand feet high, and swept on over valley and dale for hundreds of miles. As it flowed, it gathered rocks, timber, and other debris which were ground and ultimately dropped at its edges
The polar ice would have been too cold for basal movement, the viscosity is so high that the movement is planar, and the base is locked to the underlying landform. No erosion, no debris gathering or pushing. The surface would have flowed the fastest, none at the base. That's the accepted science.
On the other hand, if it is believed that ice, descending from outer space at a superrefrigerated temperature around -200°F., caused the sudden and extreme change in atmospheric temperatures, then the sudden asphyxiation and freezing of the mammoths becomes logical.
I also think there is some kind of electronic cooling that is still occuring, as the deepest permafrost is found directly under the polar auroral oval. Within that deep permafrost have been found frozen tropical forests at from 800 to 1700 feet down. This from Prudhoe bay, from drill cores:
There were palm trees, pine trees, and tropical foliage in great profusion. In fact, they found them lapped all over each other, just as though they had fallen in that position. What great catastrophe caused this massive upheaval, and then led to such dramatic changes in the climate? We stress again that everything is frozen--not petrified--and that the whole area has never once thawed since that great catastrophe took place. .......It is interesting to note that tropical ferns have been found at the Antarctic, and the evidence from these two areas, considered together, certainly suggest that there has been a dramatic change from a world wide tropical climate to an Arctic climate within datable times.
The freezing must have been instantaneous, no decay is noted, so some very large event. Makes me shiver just to think about it! And what type of event was required to cover those forests with such depths of material, and where did that material come from?
..thanks to his work my personal opinion is that the truth lies in a mixture of electric, gravitational, and mechanical forces all at work simultaneously.
The primary cause, IMO, is plasma/electricity, and from a mega CME, the ingredients entering via the poles. Heat would be removed, and charge exchanged, in large amounts. Gravity and mechanical forces might have allowed for the spreading of the ice, but not erosion if the ice was solid down to the surface. The pressure melting point may have been reached as the ice slowly warmed I suppose, and then some erosion may have occurred, but then we are back to needing the millions of years for the larger, supposedly glacial landforms to have taken shape, whereas the electrical forces could have maybe done it in a day or three?
