A previously undescribed meteorite crater having dimensions of 455 m average diameter and 31 m average depth has been discovered in northern Chile at 23°55.6′S, 68° 16.7′W. Meteorites have not been recovered, but iron shale and impactite material verify its meteoritic origin. The crater is emplaced in granite, overlain by a thin ignimbrite sheet. From the apparent disruption of the local Pleistocene drainage pattern, the age of formation of the crater must be Pleistocene or Recent. It may have been formed by the same meteoroid that created the Campo del Cielo craters in Argentina. The name Monturaqui crater is proposed.
