Dickinson County is in the south-central Upper Peninsula. It’s one of two landlocked counties in the Yoop. No Great Lakes touch its borders. Instead, the Menominee River and its tributary, the Brule River, carve its southern boundary with Wisconsin.

The Michigamme River flows along its western edge, separating it from Iron County. To the north is Marquette County and to the east / southeast is Menominee County.

Dickinson is known for its 6,400 acres of lakes and 645 miles of rivers. 

Dickinson County Formation & Naming

This county holds a unique spot in Michigan history as the youngest of the state's 83 counties. The legislature approved its creation on May 21, 1891. It became official on October 2, 1891.

The land came from Iron, Marquette, and Menominee counties. The new county was named for Don M. Dickinson, a prominent Detroit attorney who served as the U.S. Postmaster General under President Grover Cleveland.

Dickinson's political influence extended beyond the mail routes. He helped shape federal policies during a transformative era in American history.

Dickinson County Seat & Population

The county seat is Iron Mountain, a name alluding to the geological wealth beneath its streets. Founded during the iron mining boom, Iron Mountain is still the cultural and economic hub of the county.

Dickinson County has 25,947 residents, a slight decline from previous decades, according to 2020 U.S. Census data.

The population density remains low, with about 34 people per square mile. The area has a rural character and wide open spaces.

History of Dickinson County

The Ojibwe and Menominee tribes dwelled in these forests and waterways for centuries. French explorer Étienne Brûlé reached the Upper Peninsula in 1618.

However, the region remained unexploited until the late 1870s. Prospectors then discovered rich deposits of high-grade iron ore in the Menominee Iron Range.

The wilderness quickly transformed into a booming industrial frontier. Thousands of immigrants arrived from Italy, Sweden, Cornwall, and French Canada. 

Towns sprang up around the deep shaft mines. The Chapin Mine became famous as one of the wettest and most dangerous mines in the world.

Engineers built the Cornish Pump to keep water out. This architectural marvel was the largest steam-driven pumping engine ever created in the United States. 

The timber industry cleared forests to support the mines and railroads. The region became an economic powerhouse. By the mid-20th century, many mines closed.

The economy shifted toward tourism, forestry, and manufacturing. Historic downtown buildings and museum exhibits now preserve this industrial past. 

Dickinson County - Cities, Towns & Communities

Dickinson County is part of the Iron Mountain, MI-WI micropolitan statistical area. Iron Mountain is the busy county seat. Sister city Kingsford and nearby Norway are also charming locales.

Kingsford grew around a historic Ford Motor Company sawmill. Norway is known for its distinct Scandinavian heritage and its spring-fed underground lake. Smaller communities like Breen, Sagola, and Channing are quiet havens for outdoor enthusiasts.

A favorite Yooper Secret is the Millie Mine Bat Cave in Iron Mountain. This abandoned vertical mine shaft now houses one of the largest hibernating bat colonies in North America. Up to one million bats call this site home.

From the cool waters of the Menominee River to these hidden wildlife sanctuaries, Dickinson County communities preserve the industrious spirit of the Upper Peninsula.
