Macha is the name of a group of meteorite craters in the Sakha Republic of the Far Eastern Federal District of Russia.[1] The largest crater measures 300 meters in diameter and is part of a field of 5 craters, the diameters of which range from 60 to 300 meters.[2][3]

The two largest craters form the pear-shaped Abram Lake while the three remaining craters are located to the north.[4] The impact craters have been very well preserved.

The craters may have been the result of the fall of iron meteorites at approximately 5300 BCE (Holocene), which would give them an age of about 7,300 years.[1]
