An inevitable question arises: What is theage of Meteor Crater? It is certainly young,geologically speaking. The sharp angles of theboulders and smaller fragments in the rim andtalus indicate that.

J. Spencer,who was there in charge of the meteorites in the British Museum of Natural History. Below: The Ahnighito Meteorite. The Ahnighito, weighing 36I/2 tons, the largest meteoritein any museum, brought from Greenland in 1897 by Peary. Three other large iron meteorites,pretty surely of the same fall as the Ahnighito, were found nearby. Pieces of one of these hadbeen laboriously hammer off by the Eskimos for knives.
