Susquehanna Chapter ADK

On December 11, a very chilly morning, retired geology professor David Hutchison led Susquehanna Chapter hikers on an informative walk and talk about the bedrock exposed in our area and the environmental conditions that were responsible for the deposition of the sediments that formed these layers. All the bedrock that we walk on in Oneonta is composed of sedimentary rock formed about 390 to 360 million years ago during the Middle and the beginning of the Late Devonian Period of the Paleozoic Era.
