Missing Link
| Answers in Genesis
This article which has take most of its info from, 'The Lost Squadron’ Life magazine, basically tells of an expedition looking for a squadron of 8 aricraft from world war 2 in greenland. They had landed on the ice due to lack of refueling, and were left there. Fourty-six years later in 1988, the expedition found the squadron barried under 75 meters of ice, when they only expected them to be barely burried in snow.
So your 3 mile deep ice core samples may not nessisarily represent millions of years, if 75 meters of ice can be built up in only 46 years. By that amount it would only take about 3300 years to build up 3 miles of ice.
