Environmental importance

Iron Mountain's abandoned Millie Hill mine is home to one of the largest bat hibernacula in the Midwest. Roughly 25,000-50,000 bats make their winter home there. The mine is also home to the world's largest concentration of bats in the U.S. It was abandoned in the 1950s and 1960s, and is now a nature reserve. It is located on the banks of the Mississippi River, about 30 miles from the town of Iron Mountain, Illinois. It has a population of about 50,000, and has been home to bats for more than 100 years. It also has a number of other wildlife sanctuaries, such as the Redwood National Park, which is on the opposite side of the river from the mine. The abandoned mine is used by bats to hibernate in the winter, and to store food for the spring and summer. It's also a place of refuge for bats that are threatened by humans, including humans, in the United States and Canada. The area is also known as the "Bat Belt" because of the number of bats that live in the area, and because of its proximity to the Red River and the nearby Mississippi River. The Red River is a major source of drinking water for the region, as well as a source of food for many other wildlife, including bats and other bats.

Menominee Range

Iron Mountain is located within the Menominee Iron-Bearing District, which covers southern Dickinson County and extends westward into Iron County. Ore is produced from the middle Precambrian Vulcan Iron-Formation around Iron Mountain, and the Riverton Iron- formation between Iron River, Michigan and Crystal Falls, Michigan. Both formations belong to the Marquette Range Supergroup. The Vulcan is between 300 and 800 feet thick and consists of hematite and magnetite with quartz. The Riverton is 100600 feet thick. The iron ore was discovered in Dickinson County in 1849 and Iron County in1851. Iron Mountain is one of the most productive iron ore deposits in the United States. It is located in Michigan's Upper Peninsula, near the towns of Iron River and Iron Falls. The Iron Mountain Formation is between 200 and 300 feet thick, with quartz and siderite as its main constituents. The riverton is between 100 and 200 feet thick with chert and quartz as its major constituents. It belongs to the Upper Marquette Supergroup, which also includes the Iron River Iron- Formation and the Siderite-Chalcedony Formation. It was first discovered in 1851 and is located near Iron River in Michigan. It has been mined for iron ore since the early 19th century. The ore is used in the construction of roads and bridges in the area. It also provides a source of power for the town of Iron Mountain and its surrounding communities. The area is rich in iron ore.

Historical importance

Iron Mountain is home of the largest steam-driven pumping engine in the United States. Chapin Mine Steam Pump Engine (Cornish Pump) was patterned after the ones used in Cornwall in the deep tin mines. The engine's high-pressure cylinder has a 50-inch (1,300 mm) bore. The flywheel is 40 feet (12 m) in diameter, weighs 160 tons, and had an average speed of only 10 revolutions per minute. The pumping equipment utilized a reciprocating motion to a line of steel rods extending 1,500 feet (460 m) down into the mine, with eight pumps attached at intervals of 170 to 192 feet (59 m) along the rods. Each of the pumps forced the water to the next higher pump and finally out to the surface of the mine. More than a million tons of the best grade ore found in the entire mine was discovered directly below the pump, so it was essential that it be moved for excavation. In 1898 the pump was dismantled and stored away until 1907 when it was reassembled on the "C" shaft of the Chapin mine. In 1934 the pumping engine was offered to the County of Dickinson as a relic for sightseers to visit. The pump remained exposed to the elements for nearly 50 years, and in 1982 a building was constructed around the pump by the Menominee Range Historical Foundation. Today the Cornish Pumping Engine & Mining Museum exists on the site. It has been featured in the History Channel's Modern Marvels Series on the World's Biggest Machines.
