27-705: The Forestier Peninsula is a peninsula located in south-east Tasmania , Australia , approximately 60 kilometres (37 mi) by the Arthur Highway , south-east of Hobart . The peninsula is connected to mainland Tasmania at East Bay Neck , near the town of Dunalley at its northern end. At Eaglehawk Neck , the southern end of the Forestier Peninsula is connected to the Tasman Peninsula . The peninsula measures about 20 kilometres (12 mi) long by 15 kilometres (9.3 mi) wide, and

54-469: A basin . This may create peninsulas, and occurred for example in the Keweenaw Peninsula . In the case of formation from meltwater, melting glaciers deposit sediment and form moraines , which act as dams for the meltwater. This may create bodies of water that surround the land, forming peninsulas. If deposition formed the peninsula, the peninsula was composed of sedimentary rock , which

81-617: A need for educated mining professionals and directly led in 1885 to the founding of the Michigan Mining School (now Michigan Technological University ) in Houghton . Although MTU discontinued its undergraduate mining engineering program in 2006, the university continues to offer engineering degrees in a variety of other disciplines. (In 2012 mining engineering was restarted in the re-formed Department of Geological and Mining Engineering and Sciences.) Running concurrently with

108-540: A resource for functional tooling achieved popularity around 3000 B.C., during the Middle Archaic Stage. The focus of copper working seems to have gradually shifted from functional tools to ornamental objects by the Late Archaic Stage c. 1200 B.C. Native Americans would build a fire to heat the rock around and over a copper mass and, after heating, pour on cold water to crack the rock. The copper

135-598: Is a part of the Tasman municipality . The east coast of the peninsula, facing the Tasman Sea is contained within the Tasman National Park . Bay whaling activities were conducted in the coves of the peninsula in the 1830s and 1840s. Located on Forestier Peninsula facing Norfolk Bay, Flinders Bay, 8 kilometres (5.0 mi) north west of Eaglehawk Neck, was once the site of a convict Probation Station which

162-649: The Houghton micropolitan area . A small portion of the southeast of the peninsula is part of Baraga County . The peninsula measures about 150 miles (240 km) in length and about 50 miles (80 km) in width at its base. The ancient lava flows of the Keweenaw Peninsula were produced during the Mesoproterozoic Era as a part of the Midcontinent Rift between 1.096 and 1.087 billion years ago. This volcanic activity produced

189-608: The Keweenaw Waterway , a partly natural, partly artificial waterway serving as a canal. The north side of the canal is known locally as Copper Island . The cities of Houghton , the peninsula's largest population center, and Hancock , are located along the shores of the Keweenaw Waterway. Houghton is home to Michigan Technological University . The Keweenaw Peninsula is politically divided primarily between Houghton and Keweenaw counties, both of which occupy

216-572: The 16th century. A peninsula is generally defined as a piece of land surrounded on most sides by water. A peninsula may be bordered by more than one body of water, and the body of water does not have to be an ocean or a sea. A piece of land on a very tight river bend or one between two rivers is sometimes said to form a peninsula, for example in the New Barbadoes Neck in New Jersey , United States. A peninsula may be connected to

243-474: The base of the peninsula in Hancock, Michigan , where the annual snowfall average is about 220 in (560 cm). Farther north, in a community called Delaware , an unofficial average of about 240 in (610 cm) is maintained. At Delaware, the record snowfall for one season was 390 in (990 cm) in 1979. Averages over 250 in (640 cm) certainly occur in the higher elevations closer to

270-499: The case of Florida , continental drift, marine sediment, and marine transgressions were all contributing factors to its shape. In the case of formation from glaciers (e.g., the Antarctic Peninsula or Cape Cod ), peninsulas can be created due to glacial erosion , meltwater or deposition . If erosion formed the peninsula, softer and harder rocks were present, and since the glacier only erodes softer rock, it formed

297-491: The cliff line. Lake Superior significantly controls the climate of the Keweenaw Peninsula, keeping winters milder than those in surrounding areas. Spring is cool and brief, transitioning into a summer with highs near 70 °F (21 °C). Fall begins in September, with winter beginning in mid-November. The peninsula receives copious amounts of lake-effect snow from Lake Superior. Official records are maintained close to

324-540: The greater landmass of the Upper Peninsula , the Keweenaw Peninsula projects about 65 miles (105 km) northeasterly into Lake Superior , forming Keweenaw Bay . The peninsula is part of Michigan's Copper Country region, as the region was home to the first major copper mining boom in the United States. Copper mining was active in this region from the 1840s to the 1960s. The peninsula is bisected by

351-498: The hamlet of Murdunna. A historical survey map is available which outlines the geology and vegetation of Tasman Peninsula , Forestier Peninsula and south east from Coal River This Tasman Council geography article is a stub . You can help Misplaced Pages by expanding it . Peninsula The word peninsula derives from Latin paeninsula , from paene  'almost' and insula  'island'. The word entered English in

378-531: The mainland via an isthmus , for example, in the Isthmus of Corinth which connects to the Peloponnese peninsula. Peninsulas can be formed from continental drift , glacial erosion , glacial meltwater , glacial deposition , marine sediment , marine transgressions , volcanoes, divergent boundaries or river sedimentation. More than one factor may play into the formation of a peninsula. For example, in

405-490: The mining boom in the Keweenaw was the white pine lumber boom. Trees were cut for timbers for mine shafts, to heat the communities around the large copper mines, and to help build a growing nation. Much of the logging at the time was done in winter due to the ease of operability with the snow. Due to the logging practices at that time, the forest of the Keweenaw looks much different today from 100 years ago. US 41 terminates in

432-547: The north. A Keweenaw Water Trail has been established around Copper Island. The Water Trail stretches approximately 125 miles (200 km) and can be paddled in five to ten days, depending on weather and water conditions. The Keweenaw Fault runs fairly lengthwise through both Keweenaw and neighboring Houghton counties. This ancient geological slip has given rise to cliffs. U.S. Highway 41 (US 41) and Brockway Mountain Drive , north of Calumet , were constructed along

459-634: The northern Keweenaw at the Michigan State Park housing Fort Wilkins. US 41 was the so-called "Military Trail" that started in Chicago in the 1900s and ended in the Keweenaw wilderness. The restored fort has numerous exhibits. For detailed information on the region's mineralogical history, see the virtual tour of the peninsula written by the Mineralogical Society of America, found in "External links" on this page. Information on

486-458: The only strata on Earth where large-scale economically recoverable 97 percent pure native copper is found. Much of the native copper found in the Keweenaw comes in either the form of cavity fillings on lava flow surfaces, which has a ”lacy” consistency, or as "float" copper, which is found as a solid mass. Copper ore may occur within conglomerate or breccia as void or interclast fillings. The conglomerate layers occur as interbedded units within

513-409: The peninsula is sometimes referred to as Copper Island (or "Kuparisaari" by Finnish immigrants), although this term is becoming less common. It is separated from the rest of the peninsula by the Keweenaw Waterway , a natural waterway which was dredged and expanded in the 1860s across the peninsula between the cities of Houghton (named for Douglass Houghton ) on the south side and Hancock on

540-468: The sediment is deposited, forming a delta peninsula. Marine transgressions (changes in sea level) may form peninsulas, but also may affect existing peninsulas. For example, the water level may change, which causes a peninsula to become an island during high water levels. Similarly, wet weather causing higher water levels make peninsulas appear smaller, while dry weather make them appear larger. Sea level rise from global warming will permanently reduce

567-432: The size of some peninsulas over time. Peninsulas are noted for their use as shelter for humans and Neanderthals . The landform is advantageous because it gives hunting access to both land and sea animals. They can also serve as markers of a nation's borders. Keweenaw Peninsula The Keweenaw Peninsula ( / ˈ k iː w ə n ɔː / , KEE-wə-naw ) is a peninsula of the U.S. state of Michigan . Part of

594-418: The tip of the peninsula. Beginning as early as seven thousand years ago and apparently peaking around 3000 B.C., Native Americans dug copper from the southern shore of Lake Superior. This development was possible in large part because, in this region, large deposits of copper were easily accessible in surface rock and from shallow diggings. Native copper could be found as large nuggets and wiry masses. Copper as

621-525: The volcanic pile. The Keweenaw Peninsula and Isle Royale , formed by the Midcontinent Rift System, are the only sites in the United States with evidence of prehistoric aboriginal mining of copper. Artifacts made from this copper by these ancient indigenous people were traded as far south as present-day Alabama . These areas are also the unique location where chlorastrolite , the state gem of Michigan, can be found. The northern end of

648-564: The volcano erupts near shallow water. Marine sediment may form peninsulas by the creation of limestone . A rift peninsula may form as a result of a divergent boundary in plate tectonics (e.g. the Arabian Peninsula ), while a convergent boundary may also form peninsulas (e.g. Gibraltar or the Indian subcontinent ). Peninsulas can also form due to sedimentation in rivers. When a river carrying sediment flows into an ocean,

675-504: Was created from a large deposit of glacial drift . The hill of drift becomes a peninsula if the hill formed near water but was still connected to the mainland, for example during the formation of Cape Cod about 23,000 years ago. In the case of formation from volcanoes, when a volcano erupts magma near water, it may form a peninsula (e.g., the Alaskan Peninsula ). Peninsulas formed from volcanoes are especially common when

702-414: Was established in 1841. The 200 convicts were involved in timber getting and land clearing. The station, beside the mouth of Flinders Creek, was short lived and closed within several years of establishment. The convicts were transferred to the penal settlement of Port Arthur . The peninsula was severely impacted by the 2013 Tasmanian bushfires with significant property damage, particularly in and around

729-533: Was then pounded out, using rock hammers and stone chisels. The Keweenaw's rich deposits of copper (and some silver) were extracted on an industrial scale beginning around the middle of the 19th century. The industry grew through the latter part of the century and employed thousands of people well into the 20th century. Hard rock mining in the region ceased in 1967 though copper sulfide deposits continued for some time after in Ontonagon. This vigorous industry created
