Weaubleau structure, Meteorite impact site in St. Clair County, Missouri, United States
Description
The Weaubleau structure is a geological formation in Missouri created by an ancient impact event that left behind distinctive rock layers. The site displays compressed and fractured strata from different geological periods stacked in unusual arrangements across the landscape.
History
The landscape changed dramatically around 335 to 340 million years ago when a large object from space collided with this region. This collision compressed and jumbled the rock layers that originally lay flat and organized beneath the surface.
Culture
Local residents and geologists refer to specific spherical rock formations in the area as Missouri rock balls and Weaubleau eggs, which formed during the impact.
Practical
The area can be easily explored from nearby roads where rock fractures and disturbances are visible to the naked eye. The best times to visit are spring or autumn when weather is mild and views of the landscape features are clear.
Did you know?
At the center of the structure are rock formations that locals and geologists call by a distinctive nickname due to their rounded ball-like shape. These rocks formed during the impact event and stand out noticeably from the surrounding area.
