Hocking Hills State Park is Ohio’s premier scenic attraction. The geology of the area attracts thousands of visitors every year. Stunning cliffs of Mississippian-age Black Hand Sandstone (Marshall Sandstone equivalent) provide limitless opportunities to see 100-foot-high exposures displaying sedimentary, diagenetic, and erosional features. Bring your camera!
Current field trip plan
On Friday, November 6 in the afternoon to early evening, participants arrive at hotel (Sleep Inn Logan, Ohio). Visit the Hocking Hills Visitors center if you arrive before 5:00PM. Dinner is on your own but there are four walkable eateries and a brewery near the hotel. At the Sleep Inn that evening there will be a short lecture on regional and local geology to provide an overview of the trip.
Saturday, November 7 is an all-day field trip to see the Black Hand Sandstone at three or four sites with lunch (your expense) at the Hocking Hills State Park Lodge. The Lodge has great food and atmosphere with a view. In the evening there will be a group dinner (your expense) at a walkable restaurant or brewery.
