The archive is not a container for things. It is an argument about what persists. An Archive of Speculative Geologies treats geological matter as temporal evidence: jasper, agate, slag glass, and fordite photographed as if newly recovered from a future museum. Each image is assigned a taxonomic code, a temporal orientation, and a perceptual condition index. The taxonomy foregrounds structure while withholding resolution. What is presented is not another reality, but a record of how realities approach visibility and remain incomplete.
