Café examines Ohio’s famed Serpent Mound Disturbance

News Release Date: 

Researcher to discuss celestial object’s impact in southern Ohio over 250 million years ago

The Ohio State University at Marion invites the community to the Infinity Restaurant in the historic Harding Hotel, 267 West Center Street, downtown Marion, Tuesday, March 2, 7 p.m., for a free monthly community dialogue on science entitled, Science Café.

March’s Science Café welcomes Greg Schumacher from the Ohio Department of Natural Resources, Division of Geological Survey. Schumacher will lead a discussion on the fascinating history of one of Ohio's most famous geologic features entitled, “Geology of the Serpent Mound Disturbance.”

Over 250 million years ago, a huge fireball pierced the atmosphere at supersonic speeds and smashed into the vast coal swamps of prehistoric southern Ohio. In milliseconds, the Serpent Mound Disturbance was born as the exploding fireball released catastrophic forces of a scale yet to be witnessed by humankind.

Science Cafés involve lively conversations with scientists about current science topics. Science Cafés are free and open to everyone, and take place in casual settings like pubs and coffeehouses. At a café you can learn about the latest issues in science, chat with a scientist in plain language, meet new friends, speak your mind, and talk with your mouth full. The overriding goal of Ohio State Marion’s Science Café is to overcome reluctance to learning about science and to make science less mysterious.
