Lonar is located at 19°59′06″N 76°31′23″E / 19.985°N 76.52306°E / 19.985; 76.52306 (Lonar). 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 crater's 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.

Famous quotes containing the word geography:
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—Ralph Waldo Emerson (1803–1882)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
