Those who believe that the earth is less than 10,000 years old may be a little puzzled by the Greenland ice cores. At the link below, there is a description of these cores. In essence, a reliable record of more than 100,000 years can be seen before the cores become deformed and unreliable. Here is the link: ftp://ftp.ngdc.noaa.gov/paleo/icecore/greenland/summit/gisp2/depthage/countage.txt In essence the annual rings from the cores have been counted by eyeball, back to about 110,000 years. I can imagine an ardent creationist might ask who we are to believe, the YEC version of the age of the earth, or our lying eyes? Naturally this evidence contradicts Setterfield's theory also.
