A mystery called Lonar lake

Lonar Lake

Lonar lake in Maharashtra is the Earth’s only high-velocity impact crater formed in basaltic rock. It is estimated that the Lonar lake was formed 52,000 years ago by a 2 million tonnes heavy meteor traveling at a speed of 90,000 kmph. The mysterious lake is 1.8 km wide and about 150 m deep. Over time a lush green forest has surrounded this tranquil lake. This site is of the center of attraction for scientists from NASA and Geological Survey of India. 

Lonar was named after a demonic character “Lonasura” from Mahabharata and the lake also finds mention in Ramayana. Not only the lake is surrounded by ancient temples, including sculptures of Khajuraho, but is also mentioned in Rigveda, Skanda Purana, Padma Purana, and Ain-e-Akbari. The lake was rediscovered and was brought to the notice of the world by a British explorer JE Alexander in 1823.
