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 Woolsey
Mount Woolsey () is located in the Bighorn Mountains in the U.S. state of Wyoming. The peak is the third highest in the range after Cloud Peak, which is only to the south, and the summit is located in the Cloud Peak Wilderness of Bighorn National Forest. Black Tooth Mountain, the second highest mountain in the Bighorns, is an adjacent summit only to the northwest. Mount Woolsey is on a knife-like ridge known as an arête and is connected to both Black Tooth Mountain and Cloud Peak by this ridge. Along the arête is another mountain peak known as The Innominate. A small glacier lies below the arête to the southeast of Mount Woolsey.
