Pajarito Plateau
The Pajarito Plateau is a volcanic plateau in north central New Mexico, United States. The plateau, part of the Jemez Mountains, is bounded on the west by the Sierra de los Valles, the range forming the east rim of the Valles Caldera, and on the east by the Puye escarpment, which rises about above the Rio Grande valley about a mile (1.6 km) west of the river. The Rio Grande passes through White Rock Canyon to the southeast, and the Caja del Rio (Cerros del Rio) across the river is sometimes regarded as part of the plateau. The plateau is occupied by several notable entities, including Bandelier National Monument, the town of Los Alamos and its remote suburb White Rock, and Los Alamos National Laboratory. Elevations range from about 5600 feet (1700 meters) at the river to about 7800 feet (2300 meters) where the plateau merges into the mountain range. The Pajarito Plateau is primarily composed of Bandelier Tuff, a voluminous deposit of volcanic tuff laid down in an explosive er ...

Volcanic Plateau
A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus. Lava plateau Lava plateaus are formed by highly fluid basaltic lava during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions). These eruptions are quiet because of low viscosity of lava, so that it is very fluid and contains a small amount of trapped gases. The resulting sheet lava flows may be extruded from linear fissures or rifts or gigantic volcanic eruptions through multiple vents characteristic of the prehistoric era which produced giant flood basalts. Multiple successive and extensive lava flows cover the original landscape to eventually form a plateau, which may contain lava fields, cinder cones, shield volcanoes and other volcanic landforms. In some cases, a lava plateau may be part of a single volcano. An example is the massive Level Mountain shield volcano in northern British Columbia ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildlife
Wildlife refers to domestication, undomesticated animal species (biology), species, but has come to include all organisms that grow or live wilderness, wild in an area without being species, introduced by humans. Wildlife was also synonymous to game (hunting), game: those birds and mammals that were trophy hunting, hunted for sport. Wildlife can be found in all ecosystems. Deserts, plains, grasslands, woodlands, forests, and other areas, including the most developed urban areas, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that much wildlife is human impact on the environment, affected by human behavior, human activities. Some wildlife threaten human safety, health, property, and quality of life. However, many wild animals, even the dangerous ones, have value to human beings. This value might be economic, educational, or emotional in nature. Humans have historically t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rogaining
Rogaining is an orienteering sport of long distance cross-country navigation, involving both route planning and navigation between checkpoints using a variety of map types. In a rogaine, teams of two to five people choose which checkpoints to visit within a time limit with the intent of maximising their score. Teamwork, endurance, competition and an appreciation for the natural environment are features of the sport. Championship rogaines are 24 hours long, but rogaines can be as short as two hours. History Rogaining can trace its roots back to 1947 when the first of many events with some of the features of rogaines was organised by the Melbourne University Mountaineering Club. The events from the 1940s eventually led to the birth of the sport of rogaining in April 1976, in Melbourne, Australia. The sport was named, rules were adopted and the world’s first rogaining association was formed (the Victorian Rogaining Association). Growth of the association and the sport occurred ...

Orienteering
Orienteering is a group of sports that require navigational skills using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. Participants are given a topographical map, usually a specially prepared orienteering map, which they use to find control points. Originally a training exercise in land navigation for military officers, orienteering has developed many variations. Among these, the oldest and the most popular is foot orienteering. For the purposes of this article, foot orienteering serves as a point of departure for discussion of all other variations, but almost any sport that involves racing against a clock and requires navigation with a map is a type of orienteering. Orienteering is included in the programs of world sporting events including the World Games (see Orienteering at the World Games) and World Police and Fire Games. History The history of orienteering begins in the late 19th century in Swede ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endurance Riding
Endurance riding is an equestrian sport based on controlled long-distance races. It is one of the international competitions recognized by the FEI. There are endurance rides worldwide. Endurance rides can be any distance, though they are rarely over 160 km for a one-day competition. There are two main types of long-distance riding, competitive trail riding and endurance rides. In an endurance ride, discussed in this article, the winning horse is the first one to cross the finish line while stopping periodically to pass a veterinary check that deems the animal in good health and fit to continue. As with human marathon running, many riders will participate to improve their horse's personal best performance and consider finishing the distance with a proper vet completion record to be a "win". In the United States, most endurance rides are either 50 or long. Shorter rides, called Limited Distance rides (LD), are organized for new riders to the sport or young horses being ...

Ultramarathon
An ultramarathon, also called ultra distance or ultra running, is any footrace longer than the traditional marathon length of . Various distances are raced competitively, from the shortest common ultramarathon of to over . 50k and 100k are both World Athletics record distances, but some races are among the oldest and most prestigious events, especially in North America. Around 100 miles is typically the longest course distance raced in under 24 hours but there are also longer multi-day races of or more, sometimes raced in stages with breaks for sleep. While some ultras are road races, many take place on trails, leading to a large overlap with the sports of trail running and mountain running. Overview There are two main types of ultramarathon events: those that cover a specified distance or route, and those that last for a predetermined period of time (with the winner covering the most distance in that time). The most common distances are , , , and , although many races have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Distance Trail
A long-distance trail (or long-distance footpath, track, way, greenway) is a longer recreational trail mainly through rural areas used for hiking, backpacking, cycling, horse riding or cross-country skiing. They exist on all continents except Antarctica. Many trails are marked on maps. Typically, a long-distance route will be at least long, but many run for several hundred miles, or longer. Many routes are waymarked and may cross public or private land and/or follow existing rights of way. Generally, the surface is not specially prepared, and the ground can be rough and uneven in areas, except in places such as converted rail tracks or popular walking routes where stone-pitching and slabs have been laid to prevent erosion. In some places, official trails will have the surface specially prepared to make the going easier. Historically Historically, and still nowadays in countries where most people move on foot or with pack animals, long-distance trails linked far away to ...

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 ...

Tsankawi Bandelier New Mexico Worn Foot Path
Tsankawi is a detached portion of Bandelier National Monument in New Mexico, near White Rock. It is accessible from a roadside parking area just north of the intersection of East Jemez Road and State Road 4. A self-guided 1.5-mile loop trail provides access to numerous unexcavated ruins, caves carved into soft tuff, and petroglyphs. Origin of the name The name Tsankawi (''Sa'ekewikwaje Owingeh'') may mean "village between two canyons at the clump of sharp round cacti" or more simply, (''san-ke-wii'') " Opuntia sharp gap" in the Tewa language of the nearby San Idelfonso puebloans. History Tsankawi (san-KAH-wee) was built by ancient Pueblo Indians sometimes known as the Ancestral Pueblo People. Archeological evidence indicates that Tsankawi may have been constructed in the 15th century and occupied until the late 16th century—toward the end of the Rio Grande Classic Period. It was occupied by Ancestral Pueblo people. Dendrochronology (tree-ring dating) indicates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Climbing
Rock climbing is a sport in which participants climb up, across, or down natural rock formations. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes. Because of the wide range and variety of rock formations around the world, rock climbing has been separated into several different styles and sub-disciplines, such as scrambling, bouldering, sport climbing, and trad (traditional) climbing another activity involving the scaling of hills and similar formations, differentiated by the rock climber's sustained use of hands to support their body weight as well as to provide balance. Rock climbing competitions have the objectives of either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potrero (landform)
A potrero is a long mesa that at one end slopes upward to higher terrain. This landform commonly occurs on the flanks of a mountain, as part of a dissected plateau. A loan word from the Spanish language, potrero is in current use in the southwestern United States, where it is sometimes translated as "tongue of land" and "enclosed piece of pasture land". In the Spanish language, however, the "tongue of land" sense is archaic. Also archaic is the related sense of potrero referring to someone who wrangles young horses (''potros'' in Spanish) kept as breeding stock (not saddle or pack stock). In Spanish, the usual sense of ''potrero'' now refers to any land (such as a ranch, open range, or community pasture) where such horses are kept. Notable examples of potreros include some of the many mesas of the Pajarito Plateau near Santa Fe, New Mexico (United States).These "finger mesas" were once a continuous deposit of compressed volcanic ash (the Bandelier Tuff). Water then cut the tuff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
