Yorktown Formation

Photo shows the fossil-rich sediments of the mid-Piacenzian warm period (MPWP) that document the rapid warming and sea level rise between about 3.30 and 3.25 million years agao. The hammer is at the conformable boundary between the Rushmere (below) and Morgarts Beach (above) Members of the Yorktown Formation.

Socastee Formation Sampling to Study Past Records of Sea Level

In July of 2016, a team from the Climate and Land Use Research and Development Program took a trip to South Carolina to study outcrops of the “Canepatch” and “Socastee” formations along the Intra-Coastal Waterway, near Myrtle Beach. The age of these fossiliferous marine units has been controversial for several decades. To re-assess the ages of these formations, fossil
