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. [lower-alpha 1] It is either the tenth- or eleventh-highest peak in North America. 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. Its summit is a small stratovolcano on top of a high platform of sedimentary rocks. [4]

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. [2] 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. [3]

Elevation

Mount Bona's exact elevation is uncertain. USGS 1:250,000 topographical maps show an elevation of 16,421 feet (5,005 m), [5] which was determined in 1913 by International Boundary Commission surveyors. [6] However, USGS 1:63,360 topographical maps do not show a spot height, and their contour lines indicate a summit elevation of 16,550±50 feet (5045±15 meters). [7] Many sources quote the latter figure. [8]

<span class="mw-page-title-main">Wrangell Mountains</span> Mountain range in the U.S. state of Alaska

The Wrangell Mountains are a high mountain range of eastern Alaska in the United States. Much of the range is included in Wrangell-Saint Elias National Park and Preserve. The Wrangell Mountains are almost entirely volcanic in origin, and they include the second and third highest volcanoes in the United States, Mount Blackburn and Mount Sanford. The range takes its name from Mount Wrangell, which is one of the largest andesite shield volcanoes in the world, and also the only presently active volcano in the range. The Wrangell Mountains comprise most of the Wrangell Volcanic Field, which also extends into the neighboring Saint Elias Mountains and the Yukon Territory in Canada.

<span class="mw-page-title-main">Fourteener</span> Mountain peak of at least 14,000 ft.

In the mountaineering parlance of the Western United States, a fourteener is a mountain peak with an elevation of at least 14,000 ft (4267 m). The 96 fourteeners in the United States are all west of the Mississippi River. Colorado has the most (53) of any single state; Alaska is second with 29. Many peak baggers try to climb all fourteeners in the contiguous United States, one particular state, or another region.

Wrangell–St. Elias National Park and Preserve is an American national park and preserve managed by the National Park Service in south central Alaska. The park and preserve were established in 1980 by the Alaska National Interest Lands Conservation Act. The protected areas are included in an International Biosphere Reserve and are part of the Kluane/Wrangell–St. Elias/Glacier Bay/Tatshenshini-Alsek UNESCO World Heritage Site. The park and preserve form the largest area managed by the National Park Service with a total of 13,175,799.07 acres, an expanse larger than nine U.S. states and around the same size as Bosnia and Herzegovina or Croatia. 8,323,147.59 acres are designated as the national park, and the remaining 4,852,652.14 acres are designated as the preserve. The area designated as the national park alone is larger than the 47 smallest American national parks combined and is more than twice the size of all but two other national parks. Its area makes up over 15% of all national park designated land in the United States.

The Wrangell Volcanic Field is a volcanic field stretching from eastern Alaska in the United States to the southwestern Yukon Territory in Canada. The field includes the four highest volcanoes in the United States, Mount Bona, Mount Blackburn, Mount Sanford, and Mount Churchill, all of which exceed 15,000 ft in elevation. It formed as a result of subduction of the Pacific Plate beneath the North American Plate at the easternmost end of the Aleutian Trench[3].

<span class="mw-page-title-main">Mount Blackburn</span> Volcano

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 U.S. 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.

<span class="mw-page-title-main">Mount Huxley (Alaska)</span> Mountain in Alaska

Mount Huxley is a 12,216-foot glaciated mountain summit located in the Saint Elias Mountains of Wrangell-St. Elias National Park and Preserve, in the U.S. state of Alaska. The remote peak is situated 75 mi (121 km) northwest of Yakutat, and 8.7 mi (14 km) west-northwest of Mount Saint Elias. The peak rises above the Columbus Glacier and Bagley Icefield to its north, the Tyndall Glacier to the south, and the Yahtse Glacier to the west. Precipitation runoff from the mountain drains into the Gulf of Alaska. The mountain was named in 1886 by English mountaineer Harold Ward Topham for Thomas Henry Huxley (1825-1895), an English biologist. The mountain was officially named Huxley Peak in 1917, but the name was officially changed to Mount Huxley in 1968 by the U.S. Board on Geographic Names. The first ascent of the peak was made June 9, 1996 by Paul Claus who landed his plane at 11,500 feet elevation on the western flank and climbed the remaining distance to the summit. The second ascent of Mt. Huxley, and first complete ascent from base to summit, was made in June 2018 by Scott Peters, Andrew Peter, and Ben Iwrey starting from the Columbus Glacier.
