The Iron Range is collectively or individually a number of elongated iron-ore mining districts around Lake Superior in the United States and Canada. Much of the ore-bearing region lies alongside the range of granite hills formed by the Giants Range batholith . [ 1 ]
"Range" is the term commonly used for such iron ore areas around Lake Superior. In Wisconsin, the Gogebic Range is often called the Penokee Range. The range is named after Lake Gogebic, a large lake near the east end of the range in Gogebic and Ontonagon Counties in Michigan. Located within the southern of two parallel prominent ridges, the ...
Lake Superior Iron Ranges. The Vermilion Range exists between Tower, Minnesota and Ely, Minnesota, and contains significant deposits of iron ore. Together with the Mesabi, Gunflint, and Cuyuna ranges, these four constitute the Iron Ranges of northern Minnesota. While the Mesabi Range had iron ore close enough to the surface to enable pit mining ...
Lake Superior Iron Ranges. The Marquette Iron Range is a deposit of iron ore located in Marquette County, Michigan in the United States. The towns of Ishpeming and Negaunee developed as a result of mining this deposit. A smaller counterpart of Minnesota's Mesabi Range, this is one of two iron ranges in the Lake Superior basin that are in active ...
Hull–Rust–Mahoning Open Pit Iron Mine, Mesabi Range, 2010. The Mesabi Iron Range is a mining district and mountain range in northeastern Minnesota following an elongate trend containing large deposits of iron ore. It is the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota. First described in ...
The iron ore of the Cuyuna is a Lake Superior-type iron-formation similar to other iron formations in the region. [ 9 ] The Mahnomen Formation has a lower member, which lacks iron oxide components, and an upper member dominated by beds of iron oxide argillite and lean iron-formation interlayered with non-iron oxide argillite, siltstone and ...
Lake Superior deepest point [4] on the bathymetric map. [1] Lake Superior has a surface area of 31,700 square miles (82,103 km 2), [7] which is approximately the size of South Carolina or Austria. It has a maximum length of 350 statute miles (560 km; 300 nmi) and maximum breadth of 160 statute miles (257 km; 139 nmi). [8]
The Duluth Complex includes much of Minnesota's Arrowhead Region north of Lake Superior.From the west near Duluth, Minnesota, it arcs north and northeast to about 48° north latitude south of Knife Lake, proceeds east at that latitude some five to twenty kilometers distant from and south of the Canada–US border to about 90° west longitude where it joins the border at the Pigeon River, and ...
