The Tagish Meteorite was probably about 5 meters across before it entered the Earth's atmosphere. It broke apart before landing on the icy lake. Before the rising temperatures of spring melted the ice on the lake, over 500 meteorite fragments were found, 410 fragments were documented and about 200 fragments were recovered. One of the meteorite fragments appears here in the ice of Tagish Lake. The camera lense cap was placed next to the meteorite fragment for size comparison purposes.
