Lonar is located at 19°59?06?N 76°31?23?E. It has an average elevation of 563 metres (1847 feet). Lonar Lake is a saltwater lake at Lonar in Buldana district, Maharashtra, India, which was created by a meteor hitting the Earth during the Pleistocene Epoch. The impact crater thereby formed is the only hypervelocity meteoritic impact crater on basalt rock. A lake that evolved in the resulting basaltic rock formation, is both saline and alkaline in nature. Geologists, ecologists, archaeologists, naturalists and astronomers have reported several studies on the various aspects of this crater lake ecosystem. Lonar Lake has a mean diameter of 1.2 kilometres (3,900 ft) and is about 137 metres (449 ft) below the crater rim. The meteor crater rim is about 1.8 kilometres (5,900 ft) in diameter. The circular depression bears a saline water lake in its central portion. The craters age is usually estimated to be 52,000 ± 6,000 years (Pleistocene), although a study published in 2010 gives an age of 656,000 ± 81,000 years.
