“Years ago the ice used to get really thick and they had to have really long ice chisels. We would use up the whole length of the ice chisel. Now we have much shorter ice chisels and we still manage to reach the water. It seems that the overall ice thickness has lessened. Also the thickness of the ice is an indication of how cold the weather is. If it has been cold it will be thick. If it has good snow coverage it is likely to be thinner, but overall it follows the climate.”
