Greenstone Ridge Trail
The Greenstone Ridge Trail is a hiking trail on Isle Royale, in Lake Superior, northern Michigan. The island is within Isle Royale National Park. There are no roads on the island, a wilderness area and national park, so the trail doubles as the primary means of land transportation across the island. Route The trail extends from Windigo Harbor and the Windigo Ranger Station on the island's western end, east across Isle Royale, to Rock Harbor and the Rock Harbor Lodge. The Greenstone Ridge Trail generally follows the top of ''Greenstone Ridge'', a low ridge that forms the east/west spine of the island and surmounts Mount Desor, the highest point of Isle Royale. Hikers may appreciate the higher elevations as they can reduce biting mosquitoes, which are found in great numbers in the lower elevation wetlands. Natural history Hikers may see signs of the wolves and moose on Isle Royale; although scarce and shy, the woodlands that adjoin the trail are their habitat. The Green ...

Michigan
Michigan () is a state in the Great Lakes region of the upper Midwestern United States. With a population of nearly 10.12 million and an area of nearly , Michigan is the 10th-largest state by population, the 11th-largest by area, and the largest by area east of the Mississippi River.''i.e.'', including water that is part of state territory. Georgia is the largest state by land area alone east of the Mississippi and Michigan the second-largest. Its capital is Lansing, and its largest city is Detroit. Metro Detroit is among the nation's most populous and largest metropolitan economies. Its name derives from a gallicized variant of the original Ojibwe word (), meaning "large water" or "large lake". Michigan consists of two peninsulas. The Lower Peninsula resembles the shape of a mitten, and comprises a majority of the state's land area. The Upper Peninsula (often called "the U.P.") is separated from the Lower Peninsula by the Straits of Mackinac, a channel that joins Lak ...

State Gem
Leaders of states in the U.S. which have significant mineral deposits often create a state mineral, rock, stone or gemstone to promote interest in their natural resources, history, tourism, etc. Not every state has an official state mineral, rock, stone and/or gemstone, however. In the chart below, a year which is listed within parentheses represents the year during which that mineral, rock, stone or gemstone was officially adopted as a state symbol or emblem.

Chlorastrolite
Chlorastrolite, also known as Isle Royale Greenstone, is a green or bluish green stone.Arguably the rarest gemstone in the world and one of the most valuable American gemstones. The gem quality specimens are typically found on Isle Royale, a large island off the Northeastern tip of Minnesota. Michigan's State Gemstone/ref> Chlorastrolite has finely radiating or stellate (for examples, see crystal habits) masses that have a "turtleback" pattern. The stellate masses tend to be chatoyant, meaning they have a varying luster. This chatoyancy can be subtranslucent to opaque. Cholorastrolite is a variety of pumpellyite: . Chlorastrolite was once thought to be an impure variety of prehnite or thomsonite. Occurrences Chlorastrolite occurs as amygdaloid structures and fracture fillings in basalt, and when the water and wave action has worn away the basalt, they are found as beach pebbles and granules in loose sediments. It is found in the Keweenaw Peninsula of the Upper Peninsula of Michi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolves And Moose On Isle Royale
The single predator-single prey relationship between gray wolf, wolves and western moose, moose on Isle Royale in Lake Superior is unique, and has been the subject of detailed study for over 50 years. Isle Royale, the principal island of Isle Royale National Park in Michigan in the United States, is an isolated island with little wikt:migration, migration of animals into and out of the island, and as a national park, human interaction and impact on the two species is also limited. Both the wolves and the moose first became established populations on Isle Royale in the 1900s. Over the fifty years of the study, the populations of both moose and wolves have shown repeated spikes and declines and have not settled to a balanced relationship. The moose populations have ranged from 500 to 2500 while the number of wolves has ranged from almost 50 to down to two.Just 2 wolves left on Isle Royale, Detroit News, Retrieved April 18, 2016: http://www.detroitnews.com/story/news/local/michigan/2 ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosquito
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning " gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridge
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Harbor, Michigan
Rock Harbor is the main access point for visitors landing on Isle Royale in northern Lake Superior. It sits from the northeastern end of the island, the whole of which is protected as Isle Royale National Park. Two structures in Rock Harbor—the Rock Harbor Light and the Edisen Fishery—are listed on the National Register of Historic Places. The ''Rock Harbor'' name is properly applied to the inlet from Moskey Basin to Scoville Point along the southern shore of the easterly part of Isle Royale. This inlet is screened from the open waters of Lake Superior by a number of offshore islands, including Mott Island, the site of the park headquarters. Travel to Rock Harbor from the Upper Peninsula of Michigan is by the ''Ranger III'' park service ferry, operating from Houghton, Michigan, the ''Isle Royale Queen IV'' out of Copper Harbor, Michigan, and seaplane service. The ''Voyageur II'' operates out of Grand Portage, Minnesota; it circumnavigates the island with stops at W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
