That's predominently a precipitation thing. The glaciers in Ohio were stopped by warmth, not lack of precipitation. There is a large difference in latitude between the Carolinas and Southern Ohio. How far are you from Glaciers?
About 75 miles to the nearest, which are mountain glaciers. Even during the height of the Ice Age, this area was not glaciated.
The interior of Alaska was just the same during the Ice Age as now. Vegetation, loess, animals, everything. Well, there aren't mammoths or sabertooth tigers anymore, but they would be happy here if they had survived. Summer was possibly shorter then.
