“The strata of the earth is a jumbled museum. Embedded in the sediment is a text that contains limits and boundaries which evade the rationale order, and social structures which confine art. In order to read the rocks we must become conscious of geological time, and of the layers of prehistoric material that is entombed in the earth’s crust. When one scans the ruined sites of pre-history one sees a heap of wrecked maps that upsets our present art historical limits. A rubble of logic confronts the viewer as he looks into the levels of sedimentations. The abstract grids containing the raw matter are observed as something incomplete, broken and shattered.”

R.Smithson, ‘A Sedimentation of the Mind’, 1968
