Cuyuna Range

From Wikipedia, the free encyclopedia

The Croft Mine Historical Park in Crosby, Minnesota preserves the headframe and railroad bridge.

The Cuyuna Range is an iron range to the southwest of the Mesabi Range, largely within Crow Wing County, Minnesota. The range was discovered by Cuyler Adams, a surveyor who discovered traces of magnetic ore in 1895 while doing land surveys. 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. The ore was also rich in manganese, which was useful during World War I when other sources were not available. Mining on the range continued until 1984. 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.

Cuyuna Country State Recreation Area now occupies portions of the range where mining pits and rock deposit stockpiles were left behind by the miners.
