The increasing number of recognized meteorite craters indicates that these features are not so rare as formerly believed. It is probable, moreover, that meteorite craters of the geologic past were larger and more abundant than the relatively recent examples. Evidence for the fall of ancient meteorites must be sought, however, in geologic structures produced by impacts.
