Though taconite was identified as an iron-bearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn’t until then that it was extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing global economy.

Originally built in the 1870s at 214 Jackson Street in Anoka, the Jackson Hotel was destroyed in an 1884 fire. It was quickly rebuilt and continued to function as a hotel until 1975, making it a center of local commerce and social gatherings for more than ninety years.
