Sinkholes, Seeps, Stone Arches: The Splendid Karst Landscape of Fort Hill
Saturday, October 20, 2018 – 10am – 2pm
Registration will open three weeks prior to the hike
For Earth Science Week the Ohio Geological Survey participates in and leads a number of hikes across the state. Join Douglas Aden of the ODNR Geological Survey for a guided hike at Fort Hill to learn more about the splendid karst at this preserve. We will meet at the main parking lot at Fort Hill and carpool over to Circle Mound, hiking to a nearby active sinkhole that was located during Doug’s research, and then hiking over to Key Hole Arch. The total hike will be 2.5 miles and lunch will be enjoyed on the trail.
Fort Hill not only protects a 2000 year old large earthen-walled ceremonial enclosure on its flat ridgetop, but the 1400 acre preserve shelters one of the finest and oldest forests in Ohio. Eleven miles of trails immerse hikers in the beauty of Ohio’s Appalachian hill-country, the remote trails shaded by towering trees. There are many natural bridges and arches in the park which were formed when the less erosion resistant Bisher Dolomite Limestone layer eroded away beneath the more durable Peebles Dolomite Limestone layer above it.
