Though her early writing owes much to nineteenth-century American Realism, Willa Cather experiments with male and female literary traditions while finding her own modern literary voice. In the process Cather gives nature an ambivalent role in My Ántonia, O Pioneers!, and Death Comes to the Archbishop. She produces a tension between rivers and gardens, places where nature and culture converge. Like Mary Austin and Sarah Orne Jewett, Willa Cather confronts the boundaries between humans and nature.
