Puchezh-Katunki crater, Impact crater in Nizhny Novgorod Oblast, Russia.
The Puchezh-Katunki crater is an impact structure in Nizhny Novgorod Oblast with a diameter of roughly 80 kilometers. A central dome and surrounding ring formations lie beneath layers of younger sediment that accumulated over millions of years.
The crater formed roughly 195 million years ago during the Early Jurassic when a massive celestial object struck the Earth's surface. This collision left behind a major geological structure still visible in the rock layers today.
Scientists and researchers from various institutions regularly visit this geological formation to study impact processes and contribute to planetary science knowledge.
The site is challenging to visit since the impact structure lies buried beneath younger layers and most features are underground. Researchers study the location mainly through drilling and geological surveys rather than direct ground access.
The site is studied through the Vorotilovo drilling well, which reveals how the Earth's crust responded to the massive impact at considerable depths. This targeted bore hole provides unusual data about crustal deformation that would otherwise remain hidden.
