International Dark Sky Association
The International Dark-Sky Association (IDA) is a United States-based non-profit organization incorporated in 1988 by founders David Crawford, a professional astronomer, and Tim Hunter, a physician/amateur astronomer. The mission of the IDA is "to preserve and protect the night time environment and our heritage of dark skies through quality outdoor lighting." Light pollution is the result of outdoor lighting that is not properly shielded, allowing light shine into the eyes and night sky. Direct light that shines into the eyes is called glare, and light directed into the night sky above the horizon causes skyglow. Lighting can also cause light trespass when it enters areas where unwanted (e.g. a neighbor's yard and windows). IDA was the first organization in the dark-sky movement, and is currently the largest. Principal approach IDA's principal approach is to raise awareness about the value of dark, star-filled night skies and encourage their protection and restoration through ed ...

Cherry Springs State Park
Cherry Springs State Park is an Pennsylvania state park in Potter County, Pennsylvania, United States. The park was created from land within the Susquehannock State Forest, and is on Pennsylvania Route 44 in West Branch Township. Cherry Springs, named for a large stand of Black Cherry trees in the park, is atop the dissected Allegheny Plateau at an elevation of . It is popular with astronomers and stargazers for having "some of the darkest night skies on the east coast" of the United States, and was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of Parks as one of "25 Must-See Pennsylvania State Parks". The earliest recorded inhabitants of the area were the Susquehannocks, followed by the Seneca nation, who hunted there. The first settlement within the park was a log tavern built in 1818 along a trail; the trail became a turnpike by 1834 and a hotel replaced the tavern in 1874, then burned in 1897. In the late 19th a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Utah ( , ) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to its west by Nevada. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin. Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo and Ute.

Natural Bridges National Monument
Natural Bridges National Monument is a U.S. National Monument located about northwest of the Four Corners boundary of southeast Utah, in the western United States, at the junction of White Canyon and Armstrong Canyon, part of the Colorado River drainage. It features the thirteenth largest natural bridge in the world, carved from the white Permian sandstone of the Cedar Mesa Formation that gives White Canyon its name. The three bridges in the park are named ''Kachina'', ''Owachomo'', and ''Sipapu'' (the largest), which are all Hopi names. A natural bridge is formed through erosion by water flowing in the stream bed of the canyon. During periods of flash floods, particularly, the stream undercuts the walls of rock that separate the meanders (or "goosenecks") of the stream until the rock wall within the meander is undercut and the meander is cut off and the new stream bed then flows underneath the bridge. Eventually, as erosion and gravity enlarge the bridge's opening, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stewart Island / Rakiura
Stewart Island ( mi, Rakiura, ' glowing skies', officially Stewart Island / Rakiura) is New Zealand's third-largest island, located south of the South Island, across the Foveaux Strait. It is a roughly triangular island with a total land area of . Its coastline is deeply creased by Paterson Inlet (east), Port Pegasus (south), and Mason Bay (west). The island is generally hilly (rising to at Mount Anglem) and densely forested. Flightless birds, including penguins, thrive because there are few introduced predators. Almost all the island is owned by the New Zealand government and over 80 per cent of the island is set aside as the Rakiura National Park. Stewart Island's economy depends on fishing and summer tourism. Its permanent population was recorded at 408 people in the 2018 census, most of whom live in the settlement of Oban on the eastern side of the island. Ferries connect the settlement to Bluff in the South Island. Stewart Island/Rakiura is part of the Southland Dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbow Bridge National Monument
Rainbow Bridge National Monument is administered by Glen Canyon National Recreation Area, southern Utah, United States. Rainbow Bridge is often described as the world's highest natural bridge. The span of Rainbow Bridge was reported in 1974 by the Bureau of Reclamation to be , but a measurement of span according to definition by the Natural Arch and Bridge Society in 2007 resulted in a value of . At the top it is thick and wide. The bridge, which is of cultural importance to a number of area Native American tribes, has been designated a Traditional Cultural Property by the National Park Service. Size Two other natural arches, Kolob Arch and Landscape Arch, both also in southern Utah, have confirmed spans several meters longer than Rainbow Bridge, but by most definitions of the terms they are considered to be arches rather than bridges. With a height of Rainbow Bridge does indeed stand taller than either of its longer competitors, but it is outdone by Aloba Arch in Chad at ...

Pitcairn Islands
The Pitcairn Islands (; Pitkern: '), officially the Pitcairn, Henderson, Ducie and Oeno Islands, is a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The four islands—Pitcairn, Henderson, Ducie and Oeno—are scattered across several hundred miles of ocean and have a combined land area of about . Henderson Island accounts for 86% of the land area, but only Pitcairn Island is inhabited. The islands nearest to the Pitcairn Islands are Mangareva (of French Polynesia) at 688 km to the west and Easter Island at 1,929 km to the east. The Pitcairn Islanders are a biracial ethnic group descended mostly from nine ''Bounty'' mutineers and a handful of Tahitian consorts—as is still apparent from the surnames of many of the islanders. The mutiny and its aftermath have been the subject of many books and films. As of January 2020, the territory had only 47 permanent inhabitants. History Polynesi ...

Medicine Rocks State Park
Medicine Rocks State Park is a park owned by the state of Montana in the United States. It is located about west-southwest of Baker, Montana, and north of Ekalaka, Montana. The park is named for the "Medicine Rocks," a series of sandstone pillars similar to Hoodoo (geology), hoodoos some high with eerie undulations, holes, and tunnels in them.McRae and Jewell, ''Montana,'' 2009, p. 303.Hawthorn, ''Rocky Mountain States,'' 2001, p. 615.
