Of course not.

Wrong answer apparently. Take a look at post 143 above; there's no other plausible explanation other than people counting snowstorms as years.

Having refreshed my memories of the total process by reading several hundred articles in the last few days I am confident that they come close enough using current methods to satisfy any relevant argument.

There are numerous discussions regarding why the planes were found buried under ice. Remember, snowfall is not even all over Greenland and this was in the South where it's warmer and where there's more precipitation. Further North where it's colder there's less precipitation.

If Ice builds up faster it squeeshes out the bottom that much faster.

Most likely no one has ever used that part of Greenland to drill ice cores. They'd want (and need) something more stable and not as wet.
