Procedimientos de investigación para el sitio Vuelta de Obligado, San Pedro, provincia de Buenos Aires

In November 1845, a naval and terrestrial battle between the forces of the Argentinean Confederation and an Anglo-French fleet took place in Vuelta de Obligado, Province of Buenos Aires. The objects and structures which survived after this event, together with the ulterior influence of the formation processes, resulted in an archaeological site characterized by palimpsests. Moreover, this location was under the effects of several looters. Thus, most of the materials located during the archaeological works are fragmented. Up to this date, more than 300 m2 were excavated. The research was performed in different areas of the site, emphasizing the “cores of the battle”, those places used more intensively and where a major density of remains were fund. Archaeological surveys and test pits, as well as recovery of materials, were conducted along the Parana River coast. The archaeological record includes a wide variety of artifacts of glass, metal, ceramic and wood, and post traces carved in the tosca-rock, among others. In this paper, the fieldwork and cabinet research strategy employed in Vuelta de Obligado are discussed. Besides, the results obtained after fifteen years and more than twenty campaigns in this site are presented.
