Clark Mountain (California)
Clark Mountain is a mountain located in the Clark Mountain Range in the Mojave National Preserve, close to the California-Nevada border. Geography The mountain rises abruptly north of Mountain Pass and Interstate 15 to an elevation of , which is the highest point of the Mojave National Preserve and the Mojave Desert ranges. Path 46 and Path 64 (part of Path 46) 500 kV power lines run to the north and south of the mountain, respectively. Ecology The higher elevations of the mountain are a striking sky island contrast to the lower elevations of the Mojave Desert vegetation. Google Earth images. Creosote bush (''Larrea tridentata''), scrub and Joshua tree (''Yucca brevifolia'') forests grow on the foothills of the mountain while single-leaf pinyon pine (''Pinus monophylla''), Utah juniper (''Juniperus osteosperma''), and white fir (''Abies concolor'') grow on the sky island at the highest elevations. The high elevation of the mountain means that snow falls on the high p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sky Island
Sky islands are topographic isolation, isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau, and has extended to similarly isolated montane ecosystems, high-elevation forests. The isolation has significant implications for these natural habitats. The Southwestern United States, American Southwest region began warming up between and 10,000 years Before Present, BP and atmospheric temperatures increased substantially, resulting in the formation of vast deserts that isolated the sky islands. Endemism, altitudinal migration, and Relict (biology), relict populations are some of the natural phenomena to be found on sky islands. The complex dynamics of species richness on sky islands draws attention from the discipline of biogeography, and likewise the biodiversity is of concern to conservation biology. One of the key elements of a sky island is separation by physical distance from the other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sport Climbing
Sport climbing (or Bolted climbing) is a form of rock climbing that relies on permanent anchors (or bolts), permanently fixed into the rock for climber protection, in which a rope that is attached to the climber is clipped into the anchors to arrest a fall; it can also involve climbing short distances with a crash pad underneath as protection. This is in contrast to traditional climbing where climbers must place removable protection as they climb. Sport climbing usually involves lead climbing and toproping techniques, but free solo and deep-water solo (i.e. no protection) climbing on sport routes is also sometimes possible. Since sport climbing routes do not need to follow traditional climbing route lines where protection can be placed into natural features (e.g. cracks), they tend to follow more direct lines up crags. This aspect, in addition to the lack of any need to install protection during the climb (e.g. the sport climber just clips into pre-installed bolts along th ...

Suprême Jumbo Love
''Jumbo Love'' is a long sport climbing route on remote limestone cliffs on Clark Mountain in the Mojave Desert. Bolted by American climber Randy Leavitt in the 1990s, he invited Chris Sharma to attempt it in 2007. When Sharma completed the first free ascent on September 11, 2008, the route became the first-ever rock climb in history to have a confirmed grade of , and an important route in rock climbing history. The route has been repeated, and its grade confirmed, by a number of subsequent climbers, including French climber Seb Bouin, who made the fourth ascent on October 25, 2022. Bouin followed up his ascent by adding a direct start to the route on November 1, 2022, to create a route called ''Suprême Jumbo Love'', which at became North America's hardest climbing route and only the sixth 9b+ sport climbing route in history. History The original route was bolted by American climber Randy Leavitt in the late 1990s, who envisaged it being a 3-pitch climb. Leavitt fai ...

Chris Sharma
Chris Omprakash Sharma (born 23 April, 1981) is an American rock climber who is considered one of the greatest and most influential climbers in the history of the sport. He dominated sport climbing for the decade after his 2001 ascent of '' Realization/Biographie'', the world's first-ever redpoint of a consensus graded route, and ushered in what was called a "technical evolution" in the sport. Sharma carried the mantle of "world's strongest sport climber" from Wolfgang Gullich (who held it for almost a decade from the early 1980s), and passed it to Adam Ondra (who held it from 2012). In 2008, Sharma redpointed the world's first-ever consensus route with ''Jumbo Love'', and in 2013, became only the second-ever person to climb a route with ''La Dura Dura''. Sharma is also known for soloing the world's first-ever ('' Es Pontàs'' in 2007), and (''Alasha'' in 2016) deep-water solo routes. Sharma became one of the most commercially successful climbers in his sport, and was ... [...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] |

Juniperus Osteosperma
''Juniperus osteosperma'' (Utah juniper; syn. ''J. utahensis'') is a shrub or small tree native to the southwestern United States. Description The plant reaches , rarely to 9 m, tall. The shoots are fairly thick compared to most junipers, in diameter. The leaves are arranged in opposite decussate pairs or whorls of three; the adult leaves are scale-like, 1–2 mm long (to 5 mm on lead shoots) and 1–1.5 mm broad. The juvenile leaves (on young seedlings only) are needle-like, long. The cones are berry-like, in diameter, blue-brown with a whitish waxy bloom, and contain a single seed (rarely two); they mature in about 18 months and are eaten by birds and small mammals. The male cones are 2–4 mm long, and shed their pollen in early spring. It is largely monoecious with both sexes on the same plant, but around 10% of plants are dioecious, producing cones of only one sex. The plants frequently bear numerous galls caused by the juniper tip midge '' Oligot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-leaf Pinyon
''Pinus monophylla'', the single-leaf pinyon, (alternatively spelled piñon) is a pine in the pinyon pine group, native to North America. The range is in southernmost Idaho, western Utah, Arizona, southwest New Mexico, Nevada, eastern and southern California and northern Baja California. It occurs at moderate altitudes from , rarely as low as and as high as . It is widespread and often abundant in this region, forming extensive open woodlands, often mixed with junipers in the Pinyon-juniper woodland plant community. Single-leaf pinyon is the world's only one-needled pine.Gerry Moore et al. 2008 Description Species ''Pinus monophylla'' is a small to medium size tree, reaching tall and with a trunk diameter of up to rarely more. The bark is irregularly furrowed and scaly.

Yucca Brevifolia
''Yucca brevifolia'' is a plant species belonging to the genus ''Yucca''. It is tree-like in habit, which is reflected in its common names: Joshua tree, yucca palm, tree yucca, and palm tree yucca. This monocotyledonous tree is native to the arid Southwestern United States, specifically California, Arizona, Utah, and Nevada, and to northwestern Mexico It is confined mostly to the Mojave Desert between elevation. It thrives in the open grasslands of Queen Valley and Lost Horse Valley in Joshua Tree National Park. Other regions with large populations of the tree can be found northeast of Kingman, Arizona in Mohave County; and along U.S. 93 between the towns of Wickenburg and Wikieup, a route which has been designated the Joshua Tree Parkway of Arizona. The common name Joshua tree apparently comes from Christian iconography. Taxonomy The Joshua tree is also called ''izote de desierto'' (Spanish, "desert dagger").
