Macha ( Russian: Мача) is a field of five meteorite craters located 685 kilometers (425 miles) northeast 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 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]
