Semple developed a new program of research into the human aspects of geography, an innovative orientation that spanned the disciplines of geography, history, and anthropology. “”The Anglo-Saxons of the Kentucky Mountains”” (1901) exemplified this new approach. To complete research for the article, Semple traveled to the Kentucky mountains and recorded observations about aspects of mountain life, such as housing, food, crafts, and religion. This trip was itself an innovation since fieldwork was an uncommon practice in geography at the time. From her observations, Semple documented the importance human-environment interactions in character of places and regions.
