The Cuyuna Range is an iron range to the southwest of the Mesabi Range, largely within Crow Wing County, Minnesota. The Mesabi Iron Range is a vast deposit of Iron ore and the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota Crow Wing County is a County located in the US state of Minnesota. It lies along a line between Brainerd and Aitkin, although those communities are not mining towns. Brainerd is a city in Crow Wing County, Minnesota, United States. Aitkin is a city in Aitkin County, Minnesota, United States. The population was 1984 at the 2000 census Mining is the extraction of valuable Minerals or other geological materials from the earth usually (but not always from an Ore body

The range was discovered by Cuyler Adams, a surveyor who discovered traces of magnetic ore in 1895 while doing land surveys. The word "Cuyuna" was coined by Adams' wife, who combined the first three letters of Cuyler's name with "Una", the name of their dog.

Mining started on the range in 1911. The ore was located deep underground, as in the Vermilion Range, so most of the mines were developed underground or in very deep pits. The Vermilion Range exists between Tower and Ely Minnesota, and contains significant deposits of Iron ore. In addition to the iron, the ore was rich in manganese, which was useful during World War I when other sources were not available. Manganese (ˈmæŋgəniːz is a Chemical element, designated by the symbol Mn. World War I (abbreviated WWI; also known as the First World War, the Great War, and the War to End All

At the height of the mining, the Cuyuna Range was the location of the worst mining disaster in Minnesota, the Milford Mine disaster. [1] On February 5, 1924, a new tunnel was blasted too close to nearby Foley Lake, and water rushed in, killing 41 miners.

Mining on the range continued until 1984. Also like the Vermilion Range, mining slowed as it became more economical to extract taconite deposits from the Mesabi Range, which were closer to the surface. Taconite is an Iron -bearing high- Silica, Flint -like rock It is a Precambrian Sedimentary rock referred to as a Banded iron The Mesabi Iron Range is a vast deposit of Iron ore and the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota Additionally, the surface mines were safer than the mines deep underground.

Cuyuna Country State Recreation Area now occupies portions of the range where mining pits and rock deposit stockpiles were left behind by the miners. Cuyuna Country State Recreation Area is part of the Minnesota state park system in development on Minnesota State Highway 210, northeast of Brainerd The Cuyuna Lakes Trail is also located near the former mines.
