The Blithfield meteorite [1] was found by Mr. Joseph Legree in Blithfield Township, Renfrew County, Ontario and measured about 8 centimetres (3.1 in) x 10 centimetres (3.9 in) x 13.5 centimetres (5.3 in).[2] The main mass is now in the Canadian National collection, Ottawa. Blithfield is an enstatite chondrite, a group of very unusual meteorites that were formed in a very reducing atmosphere. It is a breccia, one of only five known enstatite chondrite breccias.[3]
