Devil Tower

Devils Tower rises 1267 feet above the Belle Fourche River. Once hidden, erosion has revealed Devils Tower. This 1347 acre park is covered with pine forests, woodlands, and grasslands. Deer, prairie dogs, and other wildlife are seen.

Also known as Bears Lodge, it is a sacred site for many American Indians.

President Theodore Roosevelt proclaimed Devils Tower the first national monument in 1906.

Borah Peak

The Borah Peak earthquake is the largest ever recorded in Idaho - both in terms of magnitude and in amount of property damage. It caused two deaths in Challis, about 200 kilometers northeast of Boise, and an estimated $12.5 million in damage in the Challis-Mackay area. A maximum MM intensity IX was assigned to this earthquake on the basis of surface faulting. Vibrational damage to structure was assigned intensities in the VI to VII range.

Spectacular surface faulting was associated with this earthquake - a 34-kilometer-long northwest-trending zone of fresh scarps and ground breakage on the southwest slope of the Lost River Range. The most extensive breakage occurred along the 8-kilometer zone between West Spring and Cedar Creek. Here, the ground surface was shattered into randomly tilted blocks several meters in width. The ground breakage was as wide as 100 meters and commonly had four to eight en echelon scarps as high as 1-2 meters. The throw on the faulting ranged from less than 50 centimeters on the southern-most section to 2.7 meters south of Rock Creek at the western base of Borah Peak.

Other geologic effects included rockfalls and landslides on the steep slopes of the Lost River Range, water fountains and sand boils near the geologic feature of Chilly Buttes and the Mackay Reservoir, increase or decrease in flow of water in springs, and fluctuations in well water levels. A temporary lake was formed by the rising water table south of Dickey.

Mount Baker

Mount Baker (3,285 meters; 10,778 feet) is an ice-clad volcano in the North Cascades of Washington State about 50 kilometers (31 miles) due east of the city of Bellingham. After Mount Rainier, it is the most heavily glaciated of the Cascade volcanoes: the volume of snow and ice on Mount Baker (about 1.8 cubic kilometers; 0.43 cubic miles) is greater than that of all the other Cascades volcanoes (except Rainier) combined. Isolated ridges of lava and hydrothermally altered rock, especially in the area of Sherman Crater, are exposed between glaciers on the upper flanks of the volcano: the lower flanks are steep and heavily vegetated. The volcano rests on a foundation of non-volcanic rocks in a region that is largely non-volcanic in origin.

Mount Baker is approximately 50 kilometers east of Bellingham, Washington. The best view of the mountain is from the Glacier Creek Road off of Highway 542. A 10-kilometer hike, taking off from Dead Horse Road (No.3907) affords closer views of Baker's north side. On the south side of the mountain Forest Service Road 372, taking off from Baker Lake Road, ends near the Schreibers Meadow cinder cone.

Mount Ararat

Mount Ararat (16,940 feet, 5165 m) is the largest volcano in Turkey. Although not currently active, its most recent eruption has probably been within the last 10,000 years. It is located in extreme northeastern Turkey, near the borders with Iran and Armenia. Southwest of the main peak lies Little Ararat (12,877 feet, 3896 m). Ahora Gorge is a northeast-trending chasm dropping 6000 feet from the top of the mountain and was the focus of a major earthquake in 1840. A number of claims by different explorers to have found remnants of Noah’s Ark on Mt. Ararat have led to continuing expeditions to the mountain, many of which have focused their searches on the gorge area.

Mount Elbrus

The Caucasus’ tallest mountain, Elbrus, is 5,642 meters (18,510 feet) high, higher than Western Europe’s Mt. Blanc in the Alps, the European contender if the Caucaucas are instead considered within Asia. Elbrus has two summits, the east summit being the lower of the two at 5,621 meters, both of which are dominant volcanic domes.

The Caucasus Mountains are the result of a tectonic plate collision between the Arabian plate moving northward with respect to the Eurasian plate. They form a continuation of the Himalayas, which are being pressed upwards by a similar collison zone with the Eurasian and Indian plates. The entire region is regularly subjected to strong earthquakes from this activity, especially as the fault structure is complex with the Anatolia/Turkey and Iranian Blocks flowing sidewise, which prevents subduction of the advancing plate edge and hence the lack of volcanoes

Atlas Mountains

The Atlas Mountains is a mountain range transversely a northern stretch of Africa extending concerning 2,400 km (1,500 miles) all the way through Morocco, Algeria, and Tunisia. The uppermost climax is Jbel Toubkal, with a distance from the ground of 4,167 metres (13,671 ft) in southwestern Morocco. The second highest mountain is the M'Goun of 4,071 metres (13,356 ft). The Atlas ranges divide the Mediterranean and Atlantic coastlines from the Sahara Desert. The inhabitants of the Atlas Mountains are mostly Berber tribes in Morocco and kabyles in Algeria. The vocabulary for ‘mountain’ in several Berber languages is adrar and adras, believed to be similar with the toponym.

The mountains are alienated into extra and separate ranges, as well as the Middle Atlas, High Atlas, and Anti-Atlas. The lower Tell Atlas organization close to the coast and the larger Saharan Atlas running more south terminate in the Aurès Mountains situated in Algeria and Tunisia. The Atlas Mountains compose one of the discrete physiographic provinces of the larger African Alpine System division.

Cotopaxi

Cotopaxi (0.7S 78.4W) is a stratovolcano with a summit altitude of 19,388 feet (5,911 m). It has erupted 50 times since 1738. The 1877 epidemic melted snow and ice on the summit, which produced mudflows that traveled 60 miles (100 km) from the volcano. The most topical eruption of Cotopaxi ended in 1904. Reports of an explosion in 1942 have not been confirmed. The most recent commotion was an increase in steam emissions, melting snow, and small earthquakes from 1975-1976.

Global Positioning System (GPS) receiver at Cotopaxi Volcano, Ecuador. GPS uses data transmitted by orbiting satellites to situate points on the ground. The USGS has made baseline GPS measurements at numerous volcanoes in the United States and in Latin America. In the event of an arousing of one of these volcanoes, GPS receivers would be set up at these points again to resolve whether or not computable buckle had occurred and to monitor for precursory buckle that might herald an eruption.

Mt. Whtiney

Mt. Whitney is the most frequently climbed peak in the Sierra Nevada, if not in the US. Because of this, the National Park Service and the US Forest Service, who manage the Whitney Portal Trailhead, have implemented a permit system to minimize the impact of day-hikers on the Mt. Whitney backcountry. All hikers entering the Mt. Whitney zone, including day-hikers, are required to obtain a permit—either your park wilderness permit if you are entering the zone from the west or an Inyo National Forest Whitney Zone permit if you are entering from the east.

Mt. Whitney can be most directly reached by a 10.7 mile (17.1 km) trail from Whitney Portal, 13 miles (21 km) west of the town of Lone Pine on the east side of the Sierra. Ice axes and crampons are needed in spring and early summer, but technical climbing equipment is not usually necessary between mid-July and early October. The elevation at the trailhead is 8360' (2550 meters). The elevation at the summit is 14,491' (4417 meters).

Mount Abu


The town of Mount Abu, the only hill station in Rajasthan, is located at an elevation of 1220 meters. It has been a popular retreat from the heat of Rajasthan and neighboring Gujarat for centuries. The Mount Abu Wildlife Sanctuary was established in 1960 and covers 290 km² of the mountain.

Mount Abu is home to a number of Jain temples. The Dilwara Temples are a complex of temples, carved of white marble, that were built between the 11th and 13th centuries AD. The oldest of these is the Vimal Vasahi temple, built in 1031 AD by Vimal Shah and dedicated to the first of the Jain Tirthankaras. The Lun Vasahi Temple was built in 1231 AD by the brothers Vastupal and Tejpal, who belonged to the Porwal Jain community. They were ministers of Raja Vir Dhawal, a local ruler of Gujarat.

Chinese Calender

Australia follows the Gregorian calendar. Although the People's Republic of China follows the Gregorian calendar for its day-to-day business, the dates of the Chinese New Year and other important festivals are determined by the Chinese calendar which is thought to have been invented by Emperor Huangdi, nearly 3000 years BC.

The Chinese tradition follows a different calendar to the calendar followed in Australia. The Chinese lunar year is divided into 12 months of 29 or 30 days. The calendar is adjusted to the length of the solar year by the addition of extra months at regular intervals. The years are arranged in major cycles of 60 years.

Each successive year is named after one of 12 animals, and these 12-year cycles are continuously repeated. The Chinese New Year is celebrated at the second new moon after the winter solstice and falls between 21 January and 19 February on the Gregorian calendar. The year 2008 translates to the Chinese year 4705-4706.

Mount Hood

Mount Hood from Portland, Oregon. When Mount Hood next erupts, Portland could be affected by light ashfalls similar to those it experienced during the 1980 eruptions of Mount St. Helens. The city will not be directly affected by lava flows, pyroclastic flows, or lahars, but regional transportation and water supplies could be disrupted. (Photo by David Wieprecht, USGS).

Mount Hood is more than 500,000 years old. The volcano has grown in fits and starts, with decades to centuries of frequent eruptions separated by quiet periods lasting from centuries to more than 10,000 years. In the recent past, Mount Hood has had two significant eruptive periods, one about 1,500 years ago and the other about 200 years ago.

Gasherbrum

At the head of the Baltoro Glacier, at the end of one of the world's most famed mountain walks, lies the heaviest and most remote concentration of high peaks on the planet.
Gasherbrum II is part of the greater Gasherbrum group of 5 peaks, 2 of which soar over 8000m, and is the world’s 13th highest mountain. She is roundly held as one of the most straight-forward and accessible of the fourteen, and climbers on her normal route, if sufficiently resourced and prepared, enjoy reasonable summit rates in clement weather. She is of course an 8000er, and as such repels many dozens of climbers every year. In 2004 some 38 climbers from multiple nationalities reached her summit after a small weather window opened near the end of the season.

The route of choice is the SW ridge. A mostly clearly defined spur that is relatively free of objective dangers. Nonetheless history shows more than a few climbers have perished on this route due to these causes. If you want to climb G2, you will need outstanding stamina, a fierce determination, and an ability to deal with 'expedition downtime' - boredom, apathy, lethargy, and cold lonely nights on the glacier.

8K peaks are to climbers what the Grand Slam series is to tennis players (with the exception that there are no spectators at 26,000ft). So if your not ready yet for your "Wimbledon" your not ready for G2. In real terms, you should have several serious seasons of climbing at or above 6500m before you can contemplate an ascent of Gasherbrum II or any other 8000m peak. Generally most expeditions that come here allot up to 55 days to climb this mountain from arrival in Islamabad, the capital of Pakistan.

Davis Peak

Davis Peak is a mountain just north of Diablo Lake in North Cascades National Park, in the US state of Washington. It is situated just south of the Picket variety. While not of predominantly high altitude, even for the North Cascades, it is prominent for its large, steep local respite, and in particular for its huge Northeast Face, which drops 5,250 ft (1,600 m) in one parallel mile (1.6 km). This is one of the two largest perpendicular drops in one horizontal mile in the adjacent United States, the other being the North Face of Kinnerly Peak. Davis Peak is named for the early homesteading family of Lucinda Davis, who built and ran a roadhouse for trappers, miners and other travelers at the base of the peak, near present day Diablo, prior to the influx of roads or rail, circa 1900.

Whether you are coming from the east or the west on I-90, you need to depart at Cle Elum. Look for SR 903 as it heads from Cle Elum to Rosyln. It is about 19 miles to Salmon La Sac and just before the campground and a bridge you would cross if you went too far, there is a road that angles up to the right and 1.7 miles of bumpy washboarded road will bring you to the signed exit for Davis Peak. Go left (north) and in fewer than a half mile the road descends to the TH. An extra area for parking is found just above the lower parking area and if you can't find polite parking, back track up the road to this nicer area to park. From the TH, descend to a crossing of a nice bridge that gets you nicely over the Cle Elum River.

Chimborazo

Chimborazo is situated in the Cordillera Occidental of the Andes of central Ecuador, 150 km (93 mi) south-southwest of the center Quito. It's neighbored by 5,018 m high Carihuairazo. Chimborazo's royal summit rises 2,500 m above the surrounding highlands (~3,500 to 4,000 m) with a ~20 km broad base. Under clear conditions the peak of Chimborazo can be seen from the coastal city Guayaquil. The nearest cities are Riobamba (~30km to the southeast), Ambato (~30km to the northeast) and Guaranda (~25km to the southwest).Chimborazo is bordered by the "Reserva de Produccion Faunistica Chimborazo" which forms a confined ecosystem to conserve the habitat for the andes native camelids Vicuña, Llama and Alpaca.

Chimborazo is a dominantly andesitic-dacitic stratovolcano. About 35,000 years ago a collapse of Chimborazo shaped a debris avalanche, the deposits of which underlie Riobamba. Chimborazo then erupted numerous times during the Holocene, the last time around 640 CE ± 500 years.

Castle Mountain

The Castle Mountain fault is one of several major east-northeast-striking faults in southern Alaska, and it is the only fault with historic seismicity and Holocene surface faulting (Lahr and others, 1986; Detterman and others, 1974). The Castle Mountain fault is approximately 200 km long, and is one of the longest structures in the Cook Inlet basin. Martin and Katz (1912) first noted the fault, but it was delineated on a regional scale by Detterman and others (1974, 1976). They mapped and divided it into two physiographic segments: the western Susitna Lowland and eastern Talkeetna Mountains segments (Fig. 1). Haeussler (1994, 1998) mapped and examined the 30-km-long region between the two Detterman and others (1974, 1976) maps.

This report is a compilation of the three USGS maps that cover the location of the Castle Mountain fault in some detail (Detterman and others, 1974, 1976; Haeussler, 1998), with the purpose of providing land managers with an authoritative source for the location of the fault in the Talkeetna Mountains and Susitna Lowland. There are other maps that also cover parts of the Castle Mountain fault (Reger and others, 1995a,b,c; Clardy, 1974; Fuchs, 1980), but these do not alter the location of the fault. Thus far, there are no land use or building regulations associated with proximity to the Castle Mountain fault.

The surface trace of the Castle Mountain fault is not the only earthquake hazard associated with the fault. The two historic earthquakes on the Castle Mountain fault were located on the part of the fault where there is no surface expression (Lahr and others, 1984), and thus even the part of the fault with no scarp should probably be considered active. In addition, Haeussler and others (2000) showed there is a 3-4 km wide fault-cored anticline on the north side of the fault near Houston. The faults in the core of the anticline do not crop out at the surface, but certainly also represent a seismic hazard. Saltus and others (2001) use aeromagnetic data to show that this anticline continues for the length of the Castle Mountain fault in the Susitna Lowland.

Ben Nevis

Ben Nevis at 4409ft is highest mountain in the kingdom and has some of the best climbing to be had in Scotland both summer and winter, and it is very rated by mountaineers from all over the world. It is because of this 'Highest' title that it is all the more popular, chiefly with tourists and non mountaineers alike. On its NW flank an eroded path leads many people to the summit, and it is more than customary to encounter badly equipped walkers near the summit. Everyone has a right to go there, but it is the mountains sheer status that takes away some of its charm.

However Ben Nevis has many more good points - At 4409ft 'The Ben' stands head and shoulders above all the other mountains in these islands. This elevation at such a northerly autonomy ensures an ample amount of snow for all the pleasures of winter climbing. 'The Ben' boasts more routes than any other mountain in the country. The Northern Corries of the Cairngorms may challenge this, however Ben Nevis has the height gain and lots of the routes are long and challenging. Amongst the classics are Tower Ridge a 2000ft climb that is graded Diff in summer, and GRADE III in winter. It was first climbed in 1892, or should I say descended, as it was used as a descent route by the Hopkinson Bros. Orion Direct is a 1600ft Grade V climb, and is surely one of the finest climbs of its kind in Scotland. It has been likened to having all the impression of a big alpine scale.

Mount Barney

Mount Barney is a mountain in Queensland, Australia. It lies roughly 150 kilometres south-west of Brisbane. It is a popular target for bushwalkers and rockclimbers. Mount Barney is the 7th highest mountain in Queensland and one of the most inspiring part of the Scenic Rim.

The closest town is Rathdowney. Neighboring this peak are a number of other mountains including Mount Ballow, Mount May and Mount Lindesay. The Antarctic Beech can be found of the upper slopes of both Mount Barney and in the rainforest of nearby Mount Ballow.

The scramble to the top is precisely difficult and has some sections of very steep rockclimbing and is suitable only for experienced walkers. The trail along Logan's Ridge to the summit is considered to be the most impressive. It is not suggested to ascend south-east ridge and descend Barney gorge within one day.

Adamello-Presanella

The Adamello-Presanella Group is a mountain variety in the Italian Alps. It is part of the Southern Limestone Alps. It is located in the provinces of Trento and Brescia. The name stems from its highest crests: Adamello and Presanella.

The Adamello-Presanella Group is alienated from the Ortler Alps in the north by the Tonale Pass; from the Bergamo Alps in the west by the Oglio valley (Val Camonica); from the Brenta Group in the east by the Campo Carlo Magno Pass and the river Sarca; to the south it continues towards Lake Iseo.
