Macha (Russian: Мача) is a field of five meteorite craters located 685 kilometers (425 miles) west-southwest of Yakutsk in the Sakha Republic in Siberia, Russia,[1] ranging from 60 to 300 m (200 to 980 ft) in diameter.[2][3]
The two largest craters form the pear-shaped Abram Lake while the remaining three are located to the north.[4] They have been very well preserved. The largest crater in the Macha crater field is the second-largest Holocene-era crater yet discovered, after Jinlin Crater in China.[5]
The craters are the result of the fall of possible iron meteorites at approximately 5300 BCE (Holocene), which would give them an age of about 7,300 years.[1]
