The Hill Annex Mine ceased operations in 1978. In the decades since, nature has reclaimed this abandoned Minnesota mine, and it has become a seasonal state park open to visitors from May to September.

Editor’s Note: Unfortunately, tours are no longer offered at Hill Annex Mine.

The Hill Annex Mine lies on the Mesabi Iron Range near the town of Calumet.

It was originally leased in 1892, and mining operations began in 1913.
Iron ore mining continued on and off for the next 65 years until the high-grade iron ore inevitably played out.

The operation was closed in 1978 and sold to the Iron Range Resources and Rehabilitation Board for the sum of $1.
The Board turned the former miners' clubhouse into a museum, developed and maintained a road to the taconite piles and mining structures, and began giving tours to the public.

The legislature designated Hill Annex Mine a state park in 1988, and the DNR took over operation.
Now, when you visit the park during its summer open season, you can clearly see that nature has reclaimed the mine.
