DescriptionThis is a large piece of the Bruderheim meteorite which fell on March 4th, 1960 near Bruderheim, Alberta. In total, 303 kg of fragments were found scattered over an area 3 km in length. (Such an area is called the meteorite fall's strewn field.) This specimen shows a well-developed fusion crust - the charred, charcoal-black exterior. This surface feature is acquired during a meteorite's fiery passage through the Earth's atmosphere. Meteors can enter the atmosphere at tremendous speeds, in excess of 17 km per second; at such speeds, tremendous friction with the air quickly heats their surfaces to a white-heat. A meteorite may lose most of its mass as the surface melts and is pulled away by the drag of the air.
