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

Mining on the range continued until 1984. Also like the Vermilion Range, mining slowed as it became more economical to extract taconite
