# Alpena County, Michigan

Alpena County (/ælˈpiːnə/ al-PEE-nə) is a county in the U.S. state of Michigan. As of the 2020 census, the population was 28,907. The county seat is Alpena. It is considered to be part of Northern Michigan. Alpena County comprises the Alpena, MI Micropolitan Statistical Area.

## History

The county was created by the Michigan Legislature in 1840 as Anamickee County, then renamed in 1843 to Alpena County, a pseudo-Native American word — a neologism coined by Henry Schoolcraft, meaning "a good partridge country." This was part of a much larger effort to rename a great many of the Michigan counties at the time. The Thunder Bay Band of Chippewa and Ottawa, the original indigenous inhabitants of the area, merged with the Mackinac Bands of Chippewa and Ottawa Indians in the mid 1800s under Chief Way-ge-maw-waw-be. The county was officially organized in 1857.

## Geography

According to the U.S. Census Bureau, the county has a total area of 1,695 square miles (4,390 km$^2$), of which 572 square miles (1,480 km$^2$) is land and 1,123 square miles (2,910 km$^2$) (66%) is water.
Alpena County is in the northeast of the mitten-shaped Lower Peninsula of Michigan. Lake Huron and Thunder Bay are to the east, Alcona County to the south, Oscoda County to the southwest, Montmorency County to the west, and Presque Isle County to the north. Most of the county is drained by the Thunder Bay River and its tributaries. The Mackinaw State Forest occupies large tracts of land in the county. The Thunder Bay National Marine Sanctuary is offshore adjacent to the county.
The 45th parallel bisects the county, meaning it is halfway between the North Pole and the equator.
Several islands in Thunder Bay are part of the Michigan Islands National Wildlife Refuge. There are automated lighthouses on Middle Island and Thunder Bay Island.

### Geographic features

* Thunder Bay River
* Long Lake
* Grand Lake
Glaciers shaped the area, creating a unique regional ecosystem. A large portion of the area is so-called Grayling outwash plain, consisting of broad outwash plain including sandy ice-disintegration ridges; jack pine barrens, some white pine-red pine forest, and northern hardwood forests. Large lakes were created by glacial action. Some of the inland lakes are truly massive.

The county government operates the jail, maintains rural roads, operates the major local courts, keeps files of deeds and mortgages, maintains vital records, administers public health regulations, and participates with the state in the provision of welfare and other social services. The county board of commissioners controls the budget but has only limited authority to make laws or ordinances. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street maintenance, etc. — are the responsibility of individual cities and townships.
The county operates three parks (and camp grounds) with beaches on local lakes, namely Beaver Lake Park in Lachine; Long Lake Park in Alpena; and Sunken Lake Park in Posen
