Serpent Mound crater

From Wikipedia, the free encyclopedia

Serpent Mound crater, also known as the Serpent Mound Disturbance,^[1] 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.^[2][3]

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 miles) and the age is estimated to be less than 320 million years (Mississippian or younger).^[2]

The crater is named after the Serpent Mound, an effigy mound, located on a plateau in Brush Creek Valley within the crater.
