Recent grazing impacts on the earth recorded in the Rio Cuarto crater field, ArgentinaAn anomalous alignment of oblong rimmed depressions has been observed on the otherwise featureless farmland of the Argentine Pampas. It is argued here, from sample analysis and by analogy with laboratory experiments, that the structure resulted from a low-angle impact and ricochet of a chondritic body originally 150-300 m in diameter.
