Lehigh Valley Geology Field Trips The subdued topography of the
Lehigh Valley belies the enormous thickness of sediments beneath
the ground surface, the complicated structures within and
between the buried rock units, the span of geologic time
involved in forming the rocks and their structures, and the
erosional and glacial processes that produced the major
topographic features of the familiar landscape. The area has
igneous, sedimentary and metamorphic rocks and gives easy access
to both glaciated and non-glaciated terrains. It has rocks
formed by sedimentation in both continental and marine
environments. It has everything but a currently active volcano
and a contemporary shoreline. It is, indeed, an interesting
location to study geology. Three Introductory Geology field
trips are usually run each time the course is offered. Field
Trip #1 investigates the rocks and structures within the area to
the south of the Moravian campus and involves seeing both the
oldest and the youngest rocks in the region. The olde
