Charlie Macquarie is an artist, archivist, and radio amateur (KN6HLC) who works to further smudge the already blurred lines between past and future, frequently using the landscape and built environment as a direction-finding technology for this work. He makes cultural inquiries into the historical toxins and byproducts of extractive capital through images, publications, collections of documents and sounds, and transmissions that dig into the contact zone between past and present, often engaging his family’s history as they go along. He writes scene reports, syllabi, poems, environmental impact statements, computer code, and technical documentation that further these inquiries. His work – especially the Library of Approximate Location, a series of site-specific digital and physical libraries – has been installed at missile launch facilities, cold-water geysers, bombing ranges, strip clubs, abandoned copper mines, miscellaneous holes, farms, tufa towers, rock and mineral shows, and a few art museums.
