. The continent we live on. Physical geography; Natural history. Ringed Seal. Enormous numbers of this and other species congregate each spring on the ice off these coasts to give birth and then breed again. A famous pinnacle, known as Mother Burke's Rock, near La Scie, V^hite Bay, on the rugged coast of ' â 2^s:!=:^.. of research, and the discovery of the vast Chubb Crater has played a not inconsiderable part in the formulation of this over- all picture. After much debate, and in the face of several dia- metrically opposed theories, it now seems to have been at least temporarily decided that the so-called craters that all of us can see on our satellite, the Moon, were made by meteors. This was thought to be rather odd in that the whole surface of that as- tronomical object was pock-marked with such, while our much bigger planet was not. We are now slowly changing our opinion about this. On June 20, 1943, an immense circular hole filled with water was spotted from the air by a U. S. Air Force plane at the south- eastern edge of the Ungava district. This had the usual impact ridge of shattered surface rocks piled up all around it, and it lay in an area where there was no sign of volcanic activity such as might possibly have promoted a vast crater. On being reported, its existence was doubted, but the Royal Canadian Air Force mapped it from the air in 1948, and their findings were pub- lished in 1950. An experienced prospectorâFrederick W. Chubbâ brought these to the attention of Dr. V. Ben Meen, director of the Royal Ontario Museum of Geology and Mineralogy, and these two then first flew over and later went overland (1951) to inves- tigate the discovery. It proved to be the largest meteor crater so far discovered on earth. The Canadian authorities then initiated a detailed reappraisal and examination of the aerial surveys of their country and came up with the astonishing fact that many other objects that could be meteor craters were scattered all acr
