13,000 years ago much of North America above what is the Mason-Dixon line was covered by a vast ice sheet that was some 2 miles thick. The weight of the moving ice carved out the Great Lakes and they were filled with melt water. Much of the water in the Ogallala Aquifer today is fossil water from that glacier. The glacier scraped the soil down to bedrock in some places. Today the ice has retreated and continues to melt and the land that used to be under it is still rising, a slow rebound.
