Serpent Mound crater

Serpent Mound crater is a circular geological formation in Adams County with a diameter of 8 kilometers. The impact site displays a central uplift surrounded by sedimentary rock layers, clearly marking where ancient forces transformed the landscape.

Researchers confirmed in 1961 that a meteorite impact created the structure through discovery of shatter cones and unique mineral deposits. This finding revealed how extreme cosmic collision shaped the ground beneath this part of Ohio.

Native American peoples chose this elevated area to build the famous Serpent Mound effigy, reflecting the site's importance in their worldview. The location shows how the landscape shaped where communities placed their most significant monuments.

The site can be visited year-round, though warmer months offer the most comfortable conditions for exploring the area. Visitors should arrange visits through local academic institutions that oversee the location and provide guided information.

The crater contains mineral formations that only develop when rocks are exposed to extreme pressure and heat from collision. Scientists continue to study these distinctive deposits to understand the violence of the ancient impact event.
