The Upper Peninsula of Michigan is the northern of the two major land masses that comprise the U.S. state of Michigan. It is commonly referred to as the Upper Peninsula , the U.P. , or Upper Michigan . More casually it is known as the land "above the Bridge" (above the Mackinac Bridge linking the two peninsulas). It is bounded on the north by Lake Superior, on the east by the St. Mary's River, on the south by Lake Michigan and Lake Huron, and on the west by Wisconsin.

The Upper Peninsula contains almost one-third of the land area of Michigan but just three percent of its total population. Residents are frequently called Yoopers (derived from "U.P.-ers") and have a strong regional identity. It includes the only counties in the United States where a plurality of residents claim Finnish ancestry. Large numbers of Finnish, Swedish, Danish and Norwegian emigrants came to the Upper Peninsula, especially the Keweenaw Peninsula, to work in the mines, and they stayed on and prospered even after the copper mines closed.

The peninsula's largest cities are Marquette, Escanaba, Sault Ste Marie, Menominee, Houghton, and Iron Mountain. The land and climate are not very suitable for agriculture. The economy has been based on logging, mining and tourism. Most mines have closed since the "golden age" from 1890 to 1920, and the land is heavily forested. Logging remains a major industry.

History

Main articles: Timeline of Michigan history and History of Michigan

The first known inhabitants of the Upper Peninsula were tribes speaking Algonquian languages. They arrived roughly around AD 800 and subsisted chiefly from fishing. Early tribes included the Menominee, Nocquet, and the Mishinimaki. Étienne Brûlé of France was probably the first European to visit the peninsula, crossing the St. Marys River around 1620 in search of a route to the Far East.

French colonists laid claim to the land in the 17th century, establishing missions and fur trading posts such as Sault Ste. Marie and St. Ignace. Following the end of the French and Indian War (part of the Seven Years' War) in 1763, the territory was ceded to Great Britain.

American Indian tribes formerly allied with the French were dissatisfied with the British occupation, which brought new territorial policies. Whereas the French cultivated alliances among the Indians, the British postwar approach was to treat the tribes as conquered peoples. In 1763 tribes united in Pontiac's Rebellion to try to drive the British from the area. American Indians captured Fort Michilimackinac, near present-day Mackinaw City, Michigan, then the principal fort of the British in the Michilimackinac region, as well as others and killed hundreds of British. In 1764 they began negotiations with the British which resulted in temporary peace and changes in objectionable British policies.

Although the Upper Peninsula nominally became United States territory with the 1783 Treaty of Paris, the British did not give up control until 1797 under terms of the Jay Treaty. As an American territory, the Upper Peninsula was still dominated by the fur trade. John Jacob Astor founded the American Fur Company on Mackinac Island in 1808; however, the industry began to decline in the 1830s as beaver and other game were overhunted.

When the Michigan Territory was first established in 1805, it included only the Lower Peninsula and the eastern portion of the Upper Peninsula. In 1819 the territory was expanded to include the remainder of the Upper Peninsula, all of Wisconsin, and part of Minnesota (previously included in the Indiana and Illinois Territories). When Michigan was preparing for statehood in the 1830s, the boundaries proposed corresponded to the original territorial boundaries, with some proposals even leaving the Upper Peninsula out entirely. Meanwhile, the territory was involved in a border dispute with the state of Ohio in a conflict known as the Toledo War.

The people of Michigan approved a constitution in May 1835 and elected state officials in late autumn 1835. Although the state government was not yet recognized by the United States Congress, the territorial government effectively ceased to exist. A constitutional convention of the state legislature refused a compromise to accept the full Upper Peninsula in exchange for ceding the Toledo Strip to Ohio. A second convention, hastily convened by Governor Stevens Thomson Mason, consisting primarily of Mason supporters, agreed in December 1836 to accept the U.P. in exchange for the Toledo Strip.

In January 1837, the U.S. Congress admitted Michigan as a state of the Union. At the time, Michigan was considered the losing party in the compromise. The land in the Upper Peninsula was described in a federal report as a "sterile region on the shores of Lake Superior destined by soil and climate to remain forever a wilderness."

This belief changed when rich mineral deposits (primarily copper and iron) were discovered in the 1840s. The Upper Peninsula's mines produced more mineral wealth than the California Gold Rush, especially after shipping was improved by the opening of the Soo Locks in 1855 and docks in Marquette in 1859. The Upper Peninsula supplied 90% of America's copper by the 1860s. It was the largest supplier of iron ore by the 1890s, and production continued to a peak in the 1920s, but sharply declined shortly afterward. The last copper mine closed in 1995, although the majority of mines had closed decades before. Some iron mining continues near Marquette.

Thousands of Americans and immigrants moved to the area during the mining boom, prompting the federal government to create Fort Wilkins near Copper Harbor to maintain order. The first wave were the Cornish from England, with centuries of mining experience; followed by Irish, Germans, and French Canadians. During the 1890s, Finnish immigrants began settling there in large numbers. In the early 20th century, 75% of the population was foreign-born.

Geography

The Upper Peninsula contains 16,452 square miles (42,610 km²), almost one-third of the land area of the state. The maximum east-west distance in the Upper Peninsula is about 320 miles (515 km), and the maximum north-south distance is about 125 miles (200 km). It is bounded on the north by Lake Superior, on the east by St. Mary's River, on the south by Lake Michigan and Lake Huron, and on the west by Wisconsin and (counting the water border on Lake Superior) by Minnesota. It has about 1,700 miles (2,700 km) of continuous shoreline with the Great Lakes. There are about 4,300 inland lakes, the largest of which is Lake Gogebic, and 12,000 miles (19,000 km) of streams.

The peninsula is divided between the flat, swampy areas in the east, part of the Great Lakes Plain, and the steeper, more rugged western half, called the Superior Upland, part of the Canadian Shield. The rock in the western portion is the result of volcanic eruptions and is estimated to be at least 3.5 billion years old (much older than the eastern portion) and contains the region's ore resources. A considerable amount of bedrock is visible. Mount Arvon, the highest point in Michigan, is found in the region, as well as the Porcupine and Huron Mountains. All of the higher areas are the remnants of ancient peaks, worn down over millions of years by erosion and glaciers.

The Keweenaw Peninsula is the northernmost part of the peninsula. It projects into Lake Superior and was the site of the first copper boom in the United States, part of a larger region of the peninsula called the Copper Country. Copper Island is its northernmost section.

About one third of the peninsula is government owned recreational forest land today, including the Ottawa National Forest and Hiawatha National Forest. Although heavily logged in the 19th century, the majority of the land was forested with mature trees by the 1970s.

Wildlife

The Upper Peninsula contains a large variety of wildlife. Some of the mammals found in the U.P. include shrews, moles, mice, white tailed deer, moose, black bears, gray & red foxes, wolves, river otters, martens, fishers, bobcats, coyotes, snowshoe hares, cotton-tail rabbits, chipmunks, squirrels, opossums, raccoons and bats. There is a large variety of birds, including hawks, osprey, gulls, hummingbirds, chickadees, robins, woodpeckers, warblers, and bald eagles. In terms of reptiles and amphibians, the UP has common garter snakes, red bellied snakes, pine snakes, northern water snakes, brown snakes, eastern garter snakes, eastern fox snakes, smooth green snakes, northern ringneck snakes, Eastern Milk snakes (Mackinac and Marquette counties) and Eastern Hognose snakes (Menominee County only), plus snapping turtles, wood turtles, and painted turtles (the state reptile), green frogs, bull frogs, northern leopard frogs, and salamanders. Lakes and rivers contain many fish like walleye, Northern Pike, Trout, Salmon, and bass. The UP also contains many shellfish, such as clams, aquatic snails, and crayfish.

The American Bird Conservancy and the National Audubon Society have designated several locations as internationally Important Bird Areas.

Climate

The Upper Peninsula has a humid continental climate ( Dfb in the Köppen climate classification system). The Great Lakes have a great effect on most of the peninsula. Winters tend to be long, cold, and snowy for most of the peninsul
