Trailheads
A trailhead is the point at which a trail begins, where the trail is often intended for hiking, biking, horseback riding, or off-road vehicles. Modern trailheads often contain rest rooms, maps, sign posts and distribution centers for informational brochures about the trail and its features, and parking areas for vehicles and trailers. The United States Access Board states "A trailhead is defined as an outdoor space that is designated by an entity responsible for administering or maintaining a trail to serve as an access point to the trail." The intersection of two trails is a trail junction and does not constitute a trailhead. Historically, the cities located at the terminus of major pathways for foot traffic such as the Natchez Trace and the Chisholm Trail were also known as trailheads. For mountain climbing and hiking, the elevation of the trailhead above sea level Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth ...

Trail
A trail, also known as a path or track, is an unpaved lane or small road usually passing through a natural area. In the United Kingdom and the Republic of Ireland, a path or footpath is the preferred term for a pedestrian or hiking trail. The term is also applied in North America to routes along rivers, and sometimes to highways. In the US, the term was historically used for a route into or through wild territory used by explorers and migrants (e.g. the Oregon Trail). In the United States, "trace" is a synonym for trail, as in Natchez Trace. Some trails are dedicated only for walking, cycling, horse riding, snowshoeing or cross-country skiing, but not more than one use; others, as in the case of a bridleway in the UK, are multi-use and can be used by walkers, cyclists and equestrians alike. There are also unpaved trails used by dirt bikes and other off-road vehicles, and in some places, like the Alps, trails are used for moving cattle and other livestock. Usage In Austra ...

United States Access Board
The United States Access Board (also known as the Architectural and Transportation Barriers Compliance Board) is an independent agency of the United States government devoted to accessibility for people with disabilities. The Board was created in 1973 to ensure access to federally funded facilities. It develops and maintains design criteria for the built environment, transit vehicles, telecommunications equipment, and electronic and information technology. It also provides technical assistance and training on these requirements and on accessible design and continues to enforce accessibility standards that cover federally funded facilities. The Board is structured to function as a coordinating body among federal agencies and to directly represent the public, particularly people with disabilities. Half of its members are representatives from most of the federal departments. The other half are members of the public appointed by the U.S. President, a majority of whom must have a disa ...

Natchez Trace
The Natchez Trace, also known as the Old Natchez Trace, is a historic forest trail within the United States which extends roughly from Nashville, Tennessee, to Natchez, Mississippi, linking the Cumberland, Tennessee, and Mississippi rivers. The trail was created and used by Native Americans for centuries, and was later used by early European and American explorers, traders, and emigrants in the late 18th and early 19th centuries. European Americans founded inns, also known as "stands", along the Trace to serve food and lodging to travelers. As travel shifted to steamboats on the Mississippi and other rivers, most of these stands closed. Today, the path is commemorated by the Natchez Trace Parkway, which follows the approximate path of the Trace, as well as the related Natchez Trace Trail. Parts of the original trail are still accessible, and some segments are listed on the National Register of Historic Places. Origins Largely following a geologic ridge line, prehist ...

Chisholm Trail
The Chisholm Trail was a trail used in the post-Civil War era to drive cattle overland from ranches in Texas to Kansas railheads. The trail was established by Black Beaver, a Lenape guide and rancher, and his friend Jesse Chisholm, a Cherokee merchant. They collected and drove numerous cattle along the trail to Kansas, where they could be shipped east to achieve higher prices. The southern terminus was Red River Station, a trading post near the Red River along the northern border of Texas. The northern terminus was a trading post near Kansas City, Kansas. Chisholm owned both of these posts. In the years of the cattle drives, cowboys would drive large herds from ranches across Texas to the Red River Station and then north to Kansas City. Overview Texas ranchers using the Chisholm Trail had their cowboys start cattle drives from either the Rio Grande area or San Antonio. They joined the Chisholm Trail at the Red River, at the border between Texas and Oklahoma Territory. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Height Above Average Terrain
Height above average terrain (HAAT), or (less popularly) effective height above average terrain (EHAAT), is the vertical position of an antenna site is above the surrounding landscape. HAAT is used extensively in FM radio and television, as it is more important than effective radiated power (ERP) in determining the range of broadcasts ( VHF and UHF in particular, as they are line of sight transmissions). For international coordination, it is officially measured in meters, even by the Federal Communications Commission in the United States, as Canada and Mexico have extensive border zones where stations can be received on either side of the international boundaries. Stations that want to increase above a certain HAAT must reduce their power accordingly, based on the maximum distance their station class is allowed to cover (see List of North American broadcast station classes for more information on this). The FCC procedure to calculate HAAT is: from the proposed or actual antenna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Terminology
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
