5. DISCUSSION A sand grain which exists across the "Blatt Interval" is likely to continue existing. The sand sized particles form one mode of the overall distribution curve for quartz particle sediments. Glacial crushing will convert a sand grain to fragments but no other natural process is anywhere near as efficient.
