Upper Peninsula of Michigan Northern major peninsula of the U.S. state of Michigan

The Upper Peninsulaof Michigan – also known as Upper Michigan or colloquially the U.P. – is the northern and more elevated of the two major landmasses that make up the U.S. state of Michigan; it is separated from the Lower Peninsula by the Straits of Mackinac. It is bounded primarily by Lake Superior to the north, separated from the Canadian province of Ontario at the east end by the St. Marys River, and flanked by Lake Huron and Lake Michigan along much of its south. Although the peninsula extends as a geographic feature into the state of Wisconsin, the state boundary follows the Montreal and Menominee rivers and a line connecting them.

Iron Mountain, Michigan City in Michigan, United States

Iron Mountain is a city in the U.S. state of Michigan. The population was 7,518 at the 2020 census, down from 7,624 at the 2010 census. It is the county seat of Dickinson County, in the state's Upper Peninsula. Iron Mountain was named for the valuable iron ore found in the vicinity.

Mesabi Range Mining district in northeastern Minnesota

The Mesabi Iron Range is a mining district 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 1866, it is the chief iron ore mining district in the United States. The district is located largely in Itasca and Saint Louis counties. It has been extensively worked since 1892, and has seen a transition from high-grade direct shipping ores through gravity concentrates to the current industry exclusively producing iron ore (taconite) pellets. Production has been dominantly controlled by vertically integrated steelmakers since 1901, and therefore is dictated largely by US ironmaking capacity and demand.

Iron Range Iron-ore mining districts around Lake Superior in the United States and Canada

The term Iron Range refers collectively or individually to a number of elongated iron-ore mining districts around Lake Superior in the United States and Canada. Despite the word "range", the iron ranges are not mountain chains, but outcrops of Precambrian sedimentary formations containing high percentages of iron. These cherty iron ore deposits are Precambrian in age for the Vermilion Range and middle Precambrian in age for the Mesabi and Cuyuna ranges, all in Minnesota. The Gogebic Range in Wisconsin and the Marquette Iron Range and Menominee Range in Michigan have similar characteristics and are of similar age. Natural ores and concentrates were produced from 1848 until the mid 1950s, when taconites and jaspers were concentrated and pelletized, and started to become the major source of iron production.

Iron Mountain may refer to:

Acid mine drainage Outflow of acidic water produced by sulfide oxidation from metal mines or coal mines

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.

Red Mountain (Birmingham)

Red Mountain is a long ridge running southwest-northeast and dividing Jones Valley from Shades Valley south of Birmingham, Alabama. It is part of the Ridge-and-Valley region of the Appalachian mountains. The Red Mountain Formation of hard Silurian rock strata lies exposed in several long crests, and was named "Red Mountain" because of the rust-stained rock faces and prominent seams of red hematite iron ore. The mountain was the site of the Sloss, Republic Steel, Woodward Iron and Tennessee Coal and iron mines which supplied ore to Birmingham's iron furnaces. The best displays of the mountain's geological strata occur at the Twentieth Street cut near the Vulcan statue and at the U.S. Route 31 highway cut leading into the suburb of Homewood. Most of Birmingham's television and radio stations have their transmission towers located on Red Mountain.

Zouérat Commune and town in Tiris Zemmour, Mauritania

Zouérat is the largest town in northern Mauritania and the capital of Tiris Zemmour region, with an approximate population of 44,649 (2013). It lies at the eastern end of the Mauritania Railway to Nouadhibou.

Thabazimbi Iron mining town in the Limpopo province of South Africa

Thabazimbi is an iron mining town in the Limpopo province of South Africa. The town is at the feet of the Ysterberg and is surrounded by the Witfonteinrand and Boshofberg with the majestic Kransberg in the background. The name Thabazimbi means mountain of iron because of the large iron ore reef that was discovered in 1919 by J. H. Williams. The mine boasts one of the largest mining shafts in Africa. More than 2 million tons of ore are mined every year and hauled by train to Mittal's iron and steel works. The railway line from Rustenburg reached the area in the 1930s and full scale iron and steel production began. The town was proclaimed in 1953. Kumba Iron Ore, previously Kumba Resources, is now the principal operator of the iron ore mine.

Eagle Mountain, California, is a modern-day ghost town in the California desert in Riverside County founded in 1948 by industrialist Henry J. Kaiser. The town is located at the entrance of the now-defunct Eagle Mountain iron mine, once owned by the Southern Pacific Railroad, then Kaiser Steel, and located on the southeastern corner of Joshua Tree National Park. The town's fully integrated medical care system, similar to other Kaiser operations in California, was the genesis of the modern-day Kaiser Permanente health maintenance organization. Eagle Mountain is accessible by Kaiser Road from California State Route 177, twelve miles (19 km) north of Desert Center, midway between Indio and the California/Arizona state line along Interstate 10.

Baldy Mountain (Colfax County, New Mexico)

Baldy Mountain, Baldy Peak, Mount Baldy, or Old Baldy is the highest peak in the Cimarron Range, a subrange of the Sangre de Cristo Mountains of New Mexico. It is located in Colfax County, about 6 miles (10 km) northeast of Eagle Nest. It rises abruptly, with 3,640 feet (1,110 m) of vertical relief, from the Moreno Valley to the west and has a total elevation of 12,441 feet (3,792 m).

Cuyuna Country State Recreation Area

Cuyuna Country State Recreation Area (CCSRA) is a state park unit of Minnesota, USA, being developed to rehabilitate a portion of the Cuyuna Range where mining pits and piles of waste rock were left behind after decades of open-pit mining for iron ore. Abandoned by mining companies more than 20 years ago, the state recreation area consists of regenerated vegetation and clear lakes that draw a wide range of recreation enthusiasts. The park is located off Minnesota State Highway 210, near the towns of Crosby, Ironton and Cuyuna. The Croft Mine Historical Park, formerly city-run, is now part of the state recreation area.

Tahawus, New York

Tahawus was a village in the Town of Newcomb, Essex County, New York, United States. It is now a ghost town situated in the Adirondack Park. Tahawus is located in Essex County within the unpopulated northern area designated to the town of Newcomb. Tahawus was the site of major mining and iron smelting operations in the 19th century. Although standing as recently as 2005, the last mining facilities have since been demolished and removed.

Iron Mountain Mine

Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US. Geologically classified as a "massive sulfide ore deposit", the site was mined for iron, silver, gold, copper, zinc, quartz, and pyrite intermittently from the 1860s until 1963. The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper and cadmium. One of America's most toxic waste sites, it has been listed as a federal Superfund site since 1983.

Mountain Iron Mine United States historic place

Mountain Iron Mine is a former mine in Mountain Iron, Minnesota, United States. Opened in 1892, it was the first mine on the Mesabi Range, which has proved to be the largest iron ore deposit ever discovered in the United States. Mining operations at the site ceased in 1956. The bottom of the open-pit mine has filled with water but its dimensions are readily visible. The city maintains an overlook in Mountain Iron Locomotive Park.

Gogebic Range

The Gogebic Range is an elongated area of iron ore deposits located within a range of hills in northern Michigan and Wisconsin just south of Lake Superior. It extends from Lake Namakagon in Wisconsin eastward to Lake Gogebic in Michigan, or almost 80 miles. Though long, it is only about a half mile wide and forms a crescent concave to the southeast. The Gogebic Range includes the communities of Ironwood in Michigan, plus Mellen and Hurley in Wisconsin.
