This railway has six radiating lines leaving the city of Winnipeg, and its main line connects Port Arthur on Lake Superior with Edmonton in the west.
It lies in the midst of the great red and brown hematite iron-ore deposits of the Mesabi Range - the richest in the Lake Superior district - and the mining and shipping of this ore are its principal industries.
It is found also in the Lake Superior district.
Ungava includes much of the lower portion of Labrador, with a rim of recent marine deposits along its western coast, but the interior has the usual character of low rocky hills of Archean rocks, especially granite and gneiss, with a long band of little disturbed iron-bearing rocks, resembling the Animikie, or Upper Huronian of the Lake Superior region, near its eastern side.
The iron ores are even more accessible than the famous ones of the Lake Superior region in the United States.
