The 2023 Field Conference of Pennsylvania Geologists will be held in Gettysburg, Pennsylvania. The Friday field trip will feature a Northern Central Railway train excursion and stops along the York County Heritage Rail Trail to examine the metamorphic and metaigneous rocks along this 15-mile section including a stop at Howard Tunnel, one of the oldest tunnels in the country along an active railroad. The afternoon will include several stops including the RHI Magnesite quarry in West York.
Saturday will concentrate on South Mountain in southern Adams and Franklin counties where we will examine the Proterozoic Catoctin Formation metavolcanics and overlying Earth Paleozoic rock units. Some new research has been completed in this area to whet the appetite.
