In her travels she covered the North American continent from Alaska to Panama, both coasts of South America and the interior of the southern portion, eastern, western, and southern Asia and northern Africa; and she made numerous visits to Europe. Her activity as an Alpinist began with eight ascents of first-class peaks in the Alps in 1909-10. Starting with the opportunity to climb the Matterhorn, Keen traveled to Zermattin the summer of 1909, where she climbed the Zinal Rothorn, the Monte Rosa, the Weisshorn, and the Matterhorn. In the midsummer of 1911 her inadequately outfitted expedition, hastily organized for the ascent of Mount Blackburn in Alaska, was unsuccessful, as the expedition wasted 4½ days trying to climb two different glaciers at the mountain base, compared with a total expected climb time of 12 days. Each effort was abandoned as avalanches had rendered the glaciers impassable. Keen returned early in 1912, with only local prospectors for companions, and accomplished the record first ascent of the mountain on 19 May 1912 of this sub-Arctic peak. Out of 33 days which the party spent entirely on glaciers, for 20 they were without tents, sleeping in snow caves at low temperatures in extreme storms; and for 10 days they had only candles for fuel.
Expeditions
This expedition was immediately followed by a journey of 300 miles on foot and by open, camp-built boat across the Alaskan wilderness to the Yukon River; for 125 miles the route lay over Skolai Pass, which Miss Keen was the first woman ever to cross. In 1914, with three men, she made scientific observations of the glaciers of Harriman Fjord and College Fjord, Prince William Sound, Alaska, and made the first explorations of the Harvard Glacier, reaching its sources . Miss Keen contributed numerous articles to popular and geographical magazines and lectured on her experiences. She became a fellow of the Royal Geographical Society, London, in 1914.
Personal
Keen married George Handy on 8 July 1916, in McCarthy, Alaska, within sight of Mount Blackburn. They settled in West Hartford, Vermont, and operated a farm. The couple divorced after 16 years of marriage. Following the divorce, Keen sold insurance products and continued to travel throughout the world. In 1962, at age 91, Keen set out on a world tour, to include Alaska, where she had not been since 1916.
