The timing of the Ice Age would have been controlled by the duration of the volcanism and warmer oceans. As the crust settled and the oceans cooled, the Ice Age would reach a maximum about 500 years after the Flood (based on standard heat budget equations), and then the ice sheets would melt over a 200 year period.
