This year’s field trip will focus on Cenozoic geology and paleontology along the York and Piankatank rivers in the eastern Virginia Coastal Plain. The field trip, which will be based at William & Mary, will be led by Karen Layou, Rowan Lockwood and Rick Berquist. We will examine the Haven Beach marsh deposits that are being overstepped by the beach as a result of active marine transgression. We will also visit Holland Point on the Piankatank River to see a dated oyster reef at the base of the Elsing Green Alloformation. The Mitchem pit is also on the itinerary. Here, we will see Tabb-Sedgefield spit sands over bay-bottom muddy sands of Sedgefield (or the newly named Elsing Green Formation) with assemblages of Mercenaria and numerous other shells.
Last but not least we will visit the York River State Park fossil cliffs where we will see the intriguing contact between the Yorktown-Eastover formations. We may even have a drilling demonstration at the Visitor’s Center for those who are interested.
