I was just thinking about that...!
In the summer of 2004, the North Greenland Ice Core Project cut all the way through the ice (over 10,000 feet deep) and brought up a sample of soil from the surface of Greenland (image above.) And a bit of organic matter was embedded in that first four-inch diameter sample of Greenland muck (top right image.) The organic matter might be a pine needle, a piece of bark, or possibly grass. The press release states that, "The presence of plant material under the ice indicates that the Greenland ice sheet formed relatively fast, as a slowly growing glacier would have flushed or pushed these light particles away."...
...The Antarctic ice is a bit deeper than the Greenland ice, but it, too "runs out." Before this, there is no evidence of glaciers anywhere on Earth. Standard Ice Age theory places the beginning of the Ice Ages about 2 million years ago (so far, the ice cores have drilled through 123 thousand layers in Greenland; 174 thousand layers in Antarctica.) And geology books point out that glaciation has been a rare event in Earth's history. The last episode (earlier than our very recent Ice Ages) happened before the first dinosaurs were born. Over 200 million years of Earth's prehistory passed without glaciers...
Something seems amiss here but I can't quite put my finger on it.
