Finally it meets the right bank of the Khatyrka 100 kilometres (62 mi) from its mouth, close to the northeastern end of the ridge.[2][3][4][5]

Khatyrka meteorite

The Khatyrka meteorite, a unique-type of meteorite[6] fell in the area of the Iomrautvaam river basin at 62°39′11″N 174°30′02″E / 62.65306°N 174.50056°E / 62.65306; 174.50056. It was found during an expedition to Chukotka in the summer of 2011 buried in a 7,000-year-old layer of dirt and was named Khatyrka meteorite.[7][8]
