There is a discrepancy between the soil age and the ice core data. The ice cores from Greenland show roughly 100,000 years worth of ice, indicating that either Greenland ice melts very rapidly compared to Antarctic ice or it melted off almost completely during the last interglacial.

Perhaps that particular location remained ice covered. Remember, the cores are taken at specific spots. A hundred miles away the results might be quite different. Same for the soil sample--they didn't sample all the soil everywhere under the Greenland icecap, they sampled it under the highest part of the ice sheet. > > Of course, I haven't checked these conclusions with creationist > websites, so they are provisional. ;)
