Serpent Mound crater
Serpent Mound crater, also known as the Serpent Mound Disturbance, is an eroded meteorite impact crater in Ohio, United States. It lies largely in Adams County, with the northern part mostly in Highland County, except for a small northeast part in Pike County.
It is classified as a complex crater because it features a central uplift, a transition zone, and a ring graben (a ring-shaped trough in the outer part of the crater). Although eroded, the original rim diameter is estimated at 8 km (5.0 mi) and the age is estimated to be less than 320 million years (Mississippian or younger).
