Following her husband's
ill-fated expedition to Labrador in 1903, Hubbard asked a surviving member of the party,
Dillon Wallace, to record the experience as a memorial to her husband. His published book,
Lure of the Labrador Wild was a commercial success in America, but Hubbard was not satisfied, coming to believe that Wallace was responsible for the death of her husband and that her husband's reputation had been blemished by Wallace's book. In 43 days of travelling, the Hubbard expedition confirmed that the Nascaupee, Seal Lake, and Lake Michikamau were in the same drainage basin and that the Northwest River and the Nascaupee were, in fact, the same. In addition, Hubbard made extensive notes on the topography, geology, flora, and fauna of this unknown wilderness. Her book, ''A Woman's Way Through Unknown Labrador'', and her diaries provide descriptions of her encounters with the
Naskapi and
Montagnais Indians, and of the last great herds of Labrador's
caribou. ==Later life==
