"The glacier did not erode all of the unconsolidated material in its path as it advanced southwards. Glacial
melt-water streams deposited sand gravel in preglacial river valleys. Where not eroded away, the sand and
gravel was covered by till, forming a buried valley aquifer system (Figure 3) which provides drinking water

for much of northern and eastern Morris County.”

Much of the evidence of the first two glaciations has been erased from Morris County by the action of the
Wisconsinan glacier. However isolated patches of glacial drift from the Kansan glacier have been found in
Mendham and along the North Branch of the Raritan; and of the Illinoisan just south of the Wisconsinan
terminal moraine, in Dover, Denville, and Flanders.
Management Considerations
Because natural hazards are often exaggerated by human activity, there is a need to develop legislation,
regulations, and management practices to protect human welfare as well as that of our natural resources.
