Culture
Immigrants from over 23 countries settled the area, drawn to the mining industry. By 1910 the Finns were the largest immigrant group, followed by Slovenes and Croats from the Austrian Empire, and Italians and Swedes. Over time the area developed a strong "Ranger" culture and accent. This northern Minnesota accent is still present in the area, especially among older people; hence the popular nickname "da Range".

The regional culture is strongly linked to former periods of steady, usually well-paid mining employment, although in recent decades, the region's outdoor recreation and relative remoteness has attracted new residents unconnected to the industry.
