This article examines how the colonial past manifests within the present through an analysis of ethnographic and archival fieldwork. Drawing on feminist geographic scholarship for decolonising knowledge production, I argue that geographers have a responsibility to the people they work with and the places where they conduct research to know what came before. Through an analysis of how the colonial past surfaced in everyday and ongoing experiences of negotiating consent during fieldwork, I show how reflecting on the colonial past-present offers insights into the colonial power geometries of knowledge production. Proceeding through the colonial past-present offers useful lessons on being accountable to people and lands, recognising refusal, and making autonomy. While this article is focused on my experiences as a white settler scholar from the USA who did research in a Mixe community in Oaxaca, Mexico, proceeding through colonial past-presents offers lessons to any and all geographers who struggle to unsettle the persistent colonial power geometries of knowledge production.
