Explores Thoreau's excursions as a method of travel writing, showing a literary process grounded in the emergent instability of the Anthropocene.

In the final years of his life, Henry David Thoreau outlined a unique method of writing about lived experience which touched at the fundamental nature of human life on a changing planet. The Making of Thoreau's Excursions examines the development of this literary method, the excursion, which veers away from more mainstream United States travel writing toward an ecological worldview and emerges as a dominant form in later American environmental writing.

For some 19th-century travelers, experiences beyond home presented a disturbance to more settled ways of understanding the planet. Jake McGinnis shows how authors, such as Thoreau, Margaret Fuller, Ojibwe minister George Copway, and George William Curtis, attended to these disruptions. In the excursion, the actual conditions of complex natural-cultural systems come to directly shape the ways in which a story is told. Nonfiction narrative offered a site of experimentation and adaptation, a place in which literature could respond to ecological ruptures ranging from deforestation and increased agricultural production to the disruption of Indigenous ways of living in the world.

These patterns of disturbance and adaptation, or disturbance ecologies, suggest a new form of resilience in which literary texts engage with and draw from the dynamic earthly conditions in which they are enmeshed.
