About:
• Lonar in Buldhana district, Maharashtra.
• Lonar Lake, also known as Lonar crater, was created by a meteor impact during the Pleistocene Epoch. A meteorite estimated to weigh two-million-tonnes slammed into the Earth, around 50,000 years creating a 1.83-km diameter crater where the lake formed.
• It is the only known hyper velocity meteorite crater in basaltic rock anywhere on Earth.
• It was notified as a National Geo-heritage Monument in 1979 by Geological Survey of India (GSI).
• It is famous as world’s largest basaltic impact crater. Two other similar ones are in Dhala and Ramgarh in Madhya Pradesh and Rajasthan respectively but both are relatively unknown.
• The forest-fringed lake boasts a unique ecology that is remarkably different from the rest of the flat landscape that surrounds it.
• The water sustains micro-organisms that are rarely found elsewhere on earth and the lake is also of mythological significance too.
