Mount Foraker



Mount Foraker, or Sultana as it is known by the Athabascans, stands proudly as Denali's wife. At 17,400 feet it is the sixth highest mountain in North America. Sultana was renamed in honor of Ohio senator Joseph Foraker in 1899 by Joseph Herron. Like Denali, Mount Foraker has a north and south summit at 17,400 ft. (5304m) and 16,810 ft. (5124m) respectively.

The first ascent occured in August of 1934 by Charles S. Houston, Dr. T. Graham Brown, and Chychele Waterston via the Northwest Ridge. Houston developed an interest in Foraker in the early 1930s and by the winter of 1933 was aggressively planning for his 1934 ascent. His team established a series of seven camps and summited on the 17th of August.

In the summer of 1977, George Lowe and Michael Kennedy made the first ascent of Foraker's Infinite Spur - one of the great alpine test pieces that the Alaska Range offers. And a route that remained unrepeated until Nelson's second ascent in 1988 with the late Mark Bebie. The third ascent was made in July of 2000 by Barry Blanchard and Carl Tobin. The pair shaved four days off of the original ascent. The route involves 9,000 feet of difficult climbing to Foraker's lofty 17,000 foot summit. In 2001, while continuing to make single push rapid ascents, Steve House and Rolando Garibotti completed the Infinite Spur in a blistering 25 hours. They bettered Blanchard's efforts by six days.

In mid May of 2006 Sue Nott and Karen McNeill disappeared while attempting the Infinite Spur. During search and rescue efforts footprints were found less than 1000 feet below the summit but ended abruptly. On the 11th of June search efforts were suspended.

Mount Fair weather





Mount Fairweather (officially gazetted as Fairweather Mountain in Canada but referred to as Mount Fairweather), is one of the world's highest coastal mountains at 4,671 metres (15,325 feet.) It is located 20 km (12 mi) east of the Pacific Ocean on the border of Alaska, United States and western British Columbia, Canada. Most of the mountain lies within Glacier Bay National Park and Preserve in the City and Borough of Yakutat, Alaska (USA), though the summit borders Tatshenshini-Alsek Provincial Park, British Columbia (Canada), making it the highest point in that province. It is also designated as Boundary Peak 164 or as US/Canada Boundary Point #164.

The mountain was named on May 3, 1778 by Captain James Cook,] apparently for the unusually good weather encountered at the time. The name has been translated into many languages. It was called "Mt. Beautemps" by La Perouse (1786, atlas), "Mte. Buen-tiempo" by Galiano (1802, map 3), "Gor[a]-Khoroshy-pogody" on Russian Hydrographic Dept. Chart 1378 in 1847, and "G[ora] Fayerveder" by Captain Tebenkov (1852, map 7), Imperial Russian Navy. It was called "Schonwetterberg" by Constantin Grewink in 1850 and "Schonwetter Berg" by Justus Perthes in 1882.

Fairweather was first climbed in 1931 by Allen Carpé and Terris Moore.

Geography

Mount Fairweather is located right above Glacier Bay in the Fairweather Range of the Saint Elias Mountains. Mount Fairweather also marks the northwest extremity of the Alaska Panhandle.
Like many large mountains in the St. Elias Mountains, Mount Fairweather has great vertical relief due to its dramatic rise from Glacier Bay. However, due to poor weather in the area, this effect is usually obscured with the clouds which often hides the summit from view.
Known in the Tlingit language as Tsalxhaan, it is said this mountain and Yaas'éit'aa Shaa (Mt. St. Elias) were originally next to each other but had an argument and separated. Their children, the mountains in between the two peaks, are called Tsalxhaan Yatx'i (Children of Tsalxaan.)[citation needed]

Weather

Despite its name, Mount Fairweather has generally harsh weather conditions. It receives over 100 inches (254 cm) of precipitation each year (mostly snow) and sees temperatures of around -50°F (-46°C).

Climbing history

1931 Allen Carpe and Terris Moore summited via the Southeast Ridge on June 8, 1931
1958 Paddy Sherman and 7 other Canadians reached the summit via the SE Ridge on June 26, 1958.
1968 West Ridge, Loren Adkins, Walter Gove, Paul Myhre, John Neal and Kent Stokes - summit reached June 12, 1968
1973 Southwest Ridge, Peter Metcalf, Henry Florschutz, Toby O'Brien and Lincoln Stoller. Summit reached on 10 July 1973.

Mount Churchill




Mount Churchill is a volcano in the Saint Elias Mountains and the Wrangell Volcanic Field of eastern Alaska. Churchill and its higher neighbor Mount Bona about 2 mi (3 km) to the southwest are both large ice-covered stratovolcanoes, with Churchill being the fourth highest volcano in the United States and the seventh highest in North America.

Volcanic eruptions


Mount Churchill is most noteworthy as the source of the White River Ash, deposited during two of the largest volcanic eruptions in North America during the past two millennia. This twin-lobed tephra deposit covers more than 130,000 mi² (340,000 km²) of eastern Alaska and northwestern Canada, with the northern lobe deposited 1900 years ago and extending over 250 miles (400 km) and the larger eastern lobe about 1250 years ago and stretching over 500 miles (800 km). The total volume of the ash exceeds 12 mi³ (50 km³), or roughly 50 times the volume of the 1980 eruption of Mount St. Helens, and ash layers up to 2 ft (60 cm) thick can be seen just below the surface in many roadcuts along the Alaska Highway.
The extensive ash deposits in the lowlands near the White and Yukon Rivers were first recognized in 1883, but their source remained a mystery for the next century. Geologists in the 1960s traced the two lobes of the ash back into the Saint Elias Mountains, and postulated that the ash may have come from a vent now buried under the Klutlan Glacier, which flows east for over 40 mi (64 km) from the Bona-Churchill massif into the Yukon Territory of Canada. More detailed studies in the 1990s by the U.S. Geological Survey finally produced the definitive answer. Aerial photos showed a 2.6 x 1.7 miles (4.2 x 2.7 km) elliptical, gently sloping, ice-filled depression at 14,500 ft (4400 m) just east of the present summit of Mount Churchill. This was identified as a caldera, which had formed by the collapse of the volcano's previous summit during the cataclysmic eruptions. The geological field work revealed thick young pumice deposits along the rim of the caldera which are mineralogically and chemically identical to the White River Ash.

History
Mount Churchill was first climbed in 1951 by R. Gates and J. Lindberg, but the peak was merely an unnamed satellite of Mount Bona at the time. The mountain was named in 1965 by the Alaska State Legislature for English statesman Winston Churchill.
In terms of elevation, it is a major North American peak, at well over 15,000 feet; however, in terms of topographic prominence or isolation, it is less significant, with less than a 1200 foot drop from its summit to the saddle with Bona. Churchill also lies on the northern, gentler side of the Bona massif, making it a less visually spectacular peak than some of the lower outliers of Bona such as University Peak or Aello Peak. The current standard climbing route is the South Ridge, usually as part of a climb of Mount Bona from the east starting from a ski-equipped bush plane landing at around 10,000 ft (3,000 m) on the Klutlan Glacier.

Mount Blackburn




Mount Blackburn is the highest peak in the Wrangell Mountains of Alaska in the United States. It is the fifth highest peak in the United States and the twelfth highest peak in North America. The mountain is an old, eroded shield volcano, the second highest volcano in the United States behind Mount Bona and the fifth highest in North America. It was named in 1885 by Lt. Henry T. Allen of the U.S. Army after Joseph Clay Stiles Blackburn, a U.S. senator from Kentucky. It is located in the heart of Wrangell – St. Elias National Park, the largest national park in the country.
The mountain's massif is covered almost entirely by icefields and glaciers, and is the principal source of ice for the Kennicott Glacier, which flows southeast over 20 miles (32 km) to just above the town of McCarthy. The mountain also contributes a large volume of ice to the north-flowing Nabesna Glacier and the Kuskulana Glacier system.

Mount Bona







 Mount Bona is one of the major mountains of the Saint Elias Mountains in eastern Alaska, and is the fifth highest independent peak in the United States. Mount Bona and its adjacent neighbor Mount Churchill are both large ice-covered stratovolcanoes. Bona has the distinction of being the highest volcano in the United States and the fourth highest in North America, outranked only by the three highest Mexican volcanoes, Pico de Orizaba, Popocatépetl, and Iztaccíhuatl.

The mountain's massif is covered almost entirely by icefields and glaciers, and it is the principal source of ice for the Klutlan Glacier, which flows east for over 40 miles (64 km) into the Yukon Territory of Canada. The mountain also contributes a large volume of ice to the north-flowing Russell Glacier system.

Mount Bona was named by Prince Luigi Amedeo, Duke of the Abruzzi in 1897, who saw the peak while making the first ascent of Mount Saint Elias about 80 miles (130 km) to the southeast. He named it after the Bona, his racing yacht. The mountain was first climbed in 1930 by Allen Carpé, Terris Moore, and Andrew Taylor, from the Russell Glacier on the west of the peak. The current standard route is the East Ridge; a climb of nearby Mount Churchill is a relatively easy addition via this route as well.

Zion National Park



Zion National Park

Zion National Park is a national park located in the Southwestern United States, near Springdale, Utah. A prominent feature of the 229-square-mile (593 km2) park is Zion Canyon, 15 miles (24 km) long and up to half a mile (800 m) deep, cut through the reddish and tan-colored Navajo Sandstone by the North Fork of the Virgin River. Located at the junction of the Colorado Plateau, Great Basin, and Mojave Desert regions, the park’s unique geography and variety of life zones allow for unusual plant and animal diversity. Numerous plant species as well as 289 species of birds, 75 mammals (including 19 species of bat), and 32 reptiles inhabit the park’s four life zones: desert, riparian, woodland, and coniferous forest. Common plant species include cottonwood, Cactus, Datura, Juniper, Pine, Boxelder, Sagebrush, yucca , and various willows. Notable megafauna include mountain lions, mule deer and Golden Eagles, along with reintroduced California Condors and Bighorn Sheep.

Yosemite National Park





Yosemite National Park
Yosemite National Park is a national park spanning eastern portions of Tuolumne, Mariposa and Madera counties in east central California, United States. The park covers an area of 761,266 acres (308,073 ha) and reaches across the western slopes of the Sierra Nevada mountain chain. Yosemite is visited by over 3.5 million people each year, many of whom only spend time in the seven square miles (18 km²) of Yosemite Valley. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its spectacular granitewaterfalls, clear streams, Giant Sequoia groves, and biological diversity. Almost 95% of the park is designated wilderness. Although not the first designated national park, Yosemite was a focal point in the development of the national park idea, largely owing to the work of people like John Muir and Galen Clark. cliffs,
