Mountaineering
In 1897 Mount Saint Elias () on the Alaska-Yukon border was summitted by the Duke of the Abruzzi and party. But it was not until 1913 that Denali (), the tallest peak in North America, was successfully climbed by Hudson Stuck. Mount Logan (), the tallest peak in Canada was first summitted by a half dozen climbers in 1925 in an expedition that took more than two months.
In 1879-1880 the exploration of the highest Andes in South America began when English mountaineer Edward Whymper climbed Chimborazo () and explored the mountains of Ecuador. The Cordillera between Chile and Argentina was visited by Paul Güssfeldt in 1883, who ascended the volcano Maipo () and attempted to climb the tallest mountain in the Americas, Aconcagua () that same year but was unsuccessful. The summit of Aconcagua was finally reached on January 14, 1897 by Swiss mountaineer Matthias Zurbriggen during an expedition led by Edward FitzGerald that began in December 1896. The Andes of Bolivia were first explored by Sir William Martin Conway in 1898, who later visited the mountains of Tierra del Fuego on the southern tip of South America.
Mount Harvard
In 1962, three Harvard men attempted to erect a fourteen-foot metal pole on the top of Harvard, with a sign that read "Mt. Harvard, 14,434. This sign erected at an altitude of 14,434 making it the second highest point in the contiguous United States." Before they could reach the top of the mountain darkness set in, and the group was forced to abandon the pole a few hundred yards short of the summit. The next year, two Harvard men (Tim Wirth, who later represented Colorado's Second Congressional District and then served a term in the U.S. Senate, and his brother John), along with a Cornell graduate carried the pole the extra distance, and completed the task. The pole sat on the mountain for roughly twenty years, until it disappeared at some time in the 1980s, most likely as part of an effort to clean up Colorado's fourteeners.
