Bigach Crater, Impact crater in eastern Kazakhstan.
Bigach Crater is an impact structure in eastern Kazakhstan with a diameter of roughly 8 kilometers. The circular rim has been reshaped by tectonic movement and natural weathering over millions of years.
The crater formed around 5 million years ago when a meteorite struck Earth's surface during the Pliocene epoch. Geological processes have continuously reshaped its structure since that initial impact event.
Local farming communities have adapted to the crater's terrain and use portions of it for agriculture. The formation shapes how people in nearby settlements interact with and understand their surrounding landscape.
The exposed rock surface and crater formations are accessible for geological study and observation. Visitors interested in impact structures should be prepared for a remote location with basic amenities and rugged terrain.
Tectonic faulting has given the crater an angular appearance that sets it apart from typical circular impact basins. This unusual shape results from crustal forces that reshaped the site long after the initial meteorite collision.
