All practices of design are dependent on materials and an anthropocentric way of thinking matter as mere resource, dominates. This paper attempts to counteract that mode of thinking about matter, by walking and thinking with stones, minerals and fossils, rendering matter as vibrant, arguing that a multi-scalar type of thinking is required to understand the complex issues and effects of the so-called Anthropocene. The Mineral Walk is presented as a cartographic mapping of encounters and spatio-temporal scales of a disused limestone quarry. Its sedimented walls serve as an explanatory tool that challenges linear, humancentric timescales and boundaries between human/nature, mind/ body, life/ death, past/ future; dualisms that permeates academic disciplines as well as design practices. Through the concepts introduced, this paper contributes to a formulation of a practical and theoretical framework for thinking matter otherwise. It opens up for a more entangled understanding of, and care for, human-matter relations.
