In the sequence of events in the creation-Flood Ice Age model, at the
end of deglaciation, the Ice Age was effectively over. Yet some ice
sheets continued to grow. The Greenland and Antarctica ice sheets are
remnants left over from the post-Flood Ice Age (figures 12.1 and 12.2).
They were protected from melting by their location in the polar
latitudes and by the high altitude of the ice deposited during the Ice
Age. The altitude of the ice is an important factor since the atmosphere
cools at an average of 3.6°F per 1,000 feet (6°C per 1,000 m).
It is interesting to note that the Greenland and Antarctica ice
sheets may never have grown to their present size, if it were not for
the initial thickness of ice at the end of the Ice Age. Some scientists
believe that if the ice somehow disappeared, it probably would not
return in the present climate. This is especially the case for
Greenland.

Many ice cores have been drilled deep into both the Antarctica and
Greenland ice sheets since the 1960s (see figures 12.1 and 12.2). It is
observed today that these ice sheets incorporate dust, acids, pollution,
etc. that cycle with the seasons. Near the top of the ice sheets,
annual layers can be distinguished by measuring the many variables
related to the seasons. From the top of the Greenland ice sheet,
glaciologists further claim that they can count the annual layers
downward, like counting the rings in a tree to determine its age. They
arrive at 110,000 years for the top 90 percent of the ice sheet.
