Excerpt from Weathered Zones of the Drift-Sheets of Illinois

In the case of an incomplete record it is important to determine in What way and degree it is incomplete, in order that the available record may be properly evaluated. It is also equally important to de termine, in the case of a complete record, the topographic and cli matic conditions under which the weathering took place, the dura tion of the period of weathering, and whether or not topographic changes of consequence are reflected in the record.
