I learned a couple of things on the hike. These deposits date to the Paleocene (56-66 million years ago) and apparently petrified wood from the period is rare in North America. Also, the oval cross-section of the logs is due to the fact they were deformed by pressure from the weight of deposits above them before they were mineralized. The geologists are bringing out an expect on petrified wood from North Carolina this summer to identify the tree species. They are currently guessing laurel for most of it, but want confirmation.
