Some of these are used to probe layer by layer through the concealed remains of earlier constructions, explorations, they are the tools, the icons that represent the installation, application of technology. An archaeology of implements that reference their own history, points to possible past actions, locations, cultures, industries. A site of technological construction for an end other than itself. A colonial end now forgotten, obscured in the transforming mists of time. Reverberations of generations before. An origin unrecorded, an origin deciphered by the discarded artifacts and surmised actions. A site that relies upon a discovered evidence.
