This chapter explores how maps functioned as expressions of an emergent materialist philosophy in nineteenth-century mountain writing. It identifies three forms of mapping: the paper documents carried as navigational tools, the texts produced about upland experiences, and the body. It focuses on four writers’ accounts of their travels through upland landscapes: Dorothy Wordsworth, Samuel Taylor Coleridge, John Ruskin and Elizabeth Le Blond. These accounts are distinctive in that they highlight how embodied reactions to the landscape can dramatically alter a writer’s imaginative responses. My central claim is that the mountain literatures these authors produced—in a period when the very definition and import of materialism was being significantly re-evaluated—generated a form of anticipatory cartography that understood the reading of an upland landscape as a fundamentally material experience.
