Straits Of Mackinac
The Straits of Mackinac ( ; ) are the short waterways between the U.S. state of Michigan's Upper and Lower Peninsulas, traversed by the Mackinac Bridge. The main strait is wide with a maximum depth of , and connects the Great Lakes of Lake Michigan and Lake Huron. Given the large size and configuration of the straits, hydrologically, the two connected lakes are one body of water, studied as Lake Michigan–Huron. Historically, the native Odawa people called the region around the Straits Michilimackinac. Three islands form the eastern edge of the Straits of Mackinac; two are populated— Bois Blanc Island and Mackinac Island, while the third, Round Island, is uninhabited and a designated wilderness area. The Straits of Mackinac are major shipping lanes, providing passage for raw materials and finished goods and connecting, for instance, the iron mines of Minnesota to the steel mills of Gary, Indiana. Before the railroads reached Chicago from the east, most immigrants ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Golden Gate Bridge
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the strait connecting San Francisco Bay and the Pacific Ocean in California, United States. The structure links San Francisco—the northern tip of the San Francisco Peninsula—to Marin County, California, Marin County, carrying both U.S. Route 101 in California, U.S. Route 101 and California State Route 1 across the strait. It also carries pedestrian and bicycle traffic, and is designated as part of U.S. Bicycle Route 95. Recognized by the American Society of Civil Engineers as one of the Wonders of the World, Wonders of the Modern World, the bridge is one of the most internationally recognized symbols of San Francisco and California. The idea of a fixed link between San Francisco and Marin had gained increasing popularity during the late 19th century, but it was not until the early 20th century that such a link became feasible.

Transport Hub
A transport hub is a place where passengers and cargo are exchanged between vehicles and/or between mode of transport, transport modes. Public transport hubs include train station, railway stations, metro station, rapid transit stations, bus stops, tram stops, airports, and ferry slips. Freight hubs include classification yards, airports, seaports, and truck terminals, or combinations of these. For private transport by car, the parking lot functions as an unimodal hub. History Historically, an interchange service in the scheduled passenger air transport industry involved a "through plane" flight operated by two or more airlines where a single aircraft was used with the individual airlines operating it with their own flight crews on their respective portions of a direct, no-change-of-plane multi-stop flight. In the U.S., a number of air carriers including Alaska Airlines, American Airlines, Braniff International Airways, Continental Airlines, Delta Air Lines, Eastern Airlines ...

Timber
Lumber is wood that has been processed into uniform and useful sizes (dimensional lumber), including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is referred to as timber in the United Kingdom, Australia, and New Zealand, while in other parts of the world, including the United States and Canada, the term ''timber'' refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. ''Rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. ''Finished lumber'' is supplied in standard sizes, mostly for the construction ind ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The Geology, geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock (geology), rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral or may be an aggregate (geology), aggregate of two or more different types of minerals, spaci ...

It is located in Lake Huron, at the eastern end of the Straits of Mackinac, between the state's Upper Peninsula of Michigan, Upper and Lower Peninsula of Michigan, Lower Peninsulas. The island was long home to an Odawa settlement and previous indigenous cultures before European colonization began in the 17th century. It was a strategic center of the fur trade around the Great Lakes. Based on a former trading post, Fort Mackinac was constructed on the island by the Kingdom of Great Britain, British during the American Revolutionary War. It was the site of two battles during the War of 1812 before the northern border was settled and the US gained this island in its territory. In the late 19th century, Mackinac Island became a popular tourist attraction and s ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Michilimackinac
Michilimackinac ( ) is derived from an Ottawa Ojibwe name for present-day Mackinac Island and the region around the Straits of Mackinac between Lake Huron and Lake Michigan.. Early settlers of North America applied the term to the entire region along Lakes Huron, Michigan, and Superior. Today it is considered to be mostly within the boundaries of Michigan, in the United States. Michilimackinac was the original name for present day Mackinac Island and Mackinac County.

Algonquian Peoples
The Algonquians are one of the most populous and widespread North American indigenous peoples of the Americas, indigenous American groups, consisting of the peoples who speak Algonquian languages. They historically were prominent along the East Coast of the United States, Atlantic Coast and in the interior regions along St. Lawrence River and around the Great Lakes.

List Of Longest Bridges In The World
This is a list of the world's longest bridges that are more than in length sorted by their full length above land and water. The main span is the longest span without any ground support. ''Note: There is no standard way to measure the total length of a bridge. Some bridges are measured from the beginning of the entrance ramp to the end of the exit ramp. Some are measured from shoreline to shoreline. Yet others use the length of the total construction involved in building the bridge. Since there is no standard, no ranking of a bridge should be assumed because of its position in the list. Additionally, numbers are merely estimates and measures in U.S. customary units ( feet) may be imprecise due to conversion rounding.''
