Description
TG 16–103.0 is an illustrated, one-page summary of five Susquehanna water gaps and the favored explanation for their origin. The publication is a revision of an earlier write-up that was linked to this outstanding geologic feature on the PaGEODE website. In 2016, summary sheets like this one were modified and formally published in the Pennsylvania Geological Survey’s new trail of geology series.
