Figure 69.  Examples of poor snow samples that must be discarded. A) Cutter was not inserted correctly with the back plane parallel to the snow pit face. B) Cutter was not inserted completely. C) The cutter lid was not inserted properly so that it maintained contact with the cutter, resulting in an over-sample of the snow. D) The cutter lid was not held tightly to the cutter upon removal, with a resulting loss of part of the sample.
