This expedition was immediately followed by a journey of 300 miles (483 km) on foot and by open, camp-built boat across the Alaskan wilderness to the Yukon River; for 125 miles (201 km) 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 (6100 ft) (1859 m).
