ICR acts/facts had a important article by Tim Clary (Mar) on the origin of the ice age.
I agree that the ice age coming was a post flood event, a few centuries after the flood, and that volcanoes wwre the cause of it. Now tim adds about subduction of plates etc that stirred up volcanoes and heated the oceans. I don't know if the oceans heated up but the evidence for volcanoes exploding everywhere is excellent. in fact the fossil assemblages found in N America are from this covering of ash. it then follows that so much stufff in the air, rotation of it to the pole directions, would allow a century or two of ice age conditions. Then a sudden melt.
I suggest the melt is the origin for all glacial landscaping that is not attributed to slow moving glaciers.
