It is 4 kilometres (2.5 mi) in diameter and its age is estimated to be about 455 million years (Late Ordovician). The crater is not exposed at the surface.[1]

Its formation has been associated with the breakdown of 100km asteroid, that might have also resulted in the Tvären and Lockne craters in Sweden among others.[2]
