This collaboration between ERRE and David Taylor took the artists on a journey from the Pacific coast to the Gulf of Mexico as they traced the U.S.-Mexico border line as it was recognized between the two nations between 1821 and 1848. The artist’s marked the historic boundary with 47 metal obelisks made to imitate the 276 stone and iron markers erected along the current border — which was established in 1848. The 47 monuments were placed at different sites, some remote, some more densely populated in various locations and towns in the U.S. The purpose was to make these forgotten, historic national limits visible both through the markers an through a photographic record that has been exhibited widely. The impermanence of the monuments underscore the temporary nature of borders.
