About Logancha
Logancha Crater
The Logancha Crater is an impact structure located within the Krasnoyarsk region of Russia. It is recognized as a confirmed impact crater, although its features are not visible on the Earth's surface today, suggesting it is either buried or has undergone significant erosion.
Key Characteristics
The crater measures approximately 20 kilometers (12 miles) in diameter. Its geological age is estimated to be around 40 million years, with a possible range of 20 million years older or younger (40 ± 20 million years). The fact that it is not exposed at the surface indicates that subsequent geological processes have obscured its original form.
Significance
While specific details about its discovery and the celestial body that formed it are not provided, the Logancha Crater represents another piece of evidence for impact events that have shaped the Earth's surface over geological time. Its buried nature makes it a subject of interest for geophysical research aimed at understanding subsurface structures.

Related Impact Craters
Jänisjärvi
Jänisjärvi is a lake in the Republic of Karelia, Russia, whose basin was formed by a meteorite impact approximately 700 million years ago. The impact created a circular crater with a diameter of 14 kilometers. It was once mistakenly identified as a volcanic caldera before its true impact origin was recognized.
Kara
Kara is a heavily eroded meteorite crater located in the Yugorsky Peninsula, Nenetsia, Russia. While its current diameter is estimated at 65 kilometers, it is believed to have originally been 120 kilometers before significant erosion. The impact event occurred approximately 70.3 million years ago during the Late Cretaceous period.
Puchezh-Katunki
The Puchezh-Katunki crater is a large impact structure located in the Nizhny Novgorod Oblast of Russia, with a current estimated diameter of 80 kilometers. Its formation is dated to the Early Jurassic period, approximately 195.9 million years ago. Despite its significant size, the crater is largely buried by younger sediments, with its presence primarily indicated by variations in surface vegetation.
