Abstract

Synopsis:

First - In Warren County the drift is of uneven depth. As in other drift areas, this unevenness is not dependent entirely on the pre-glacial surface. In the unconformity of the drift on this pre-glacial surface a relation is seen indicating a similarity between the present drainage system and the pre-glacial drainage system. Second - The present river valleys and larger ravines are larger than present streams require. They fit into the pre-glacial valleys. Third - ln the smaller ravines only do we find erosion without regard to the pre-glacial configuration of the county.
