Cave of Arica The Cave of Arica is an archaeological and geological site on the Pacific coast near Arica, Chile, notable for stratified human burials, mummified remains, and lithic assemblages that illuminate preceramic and formative periods in northern Chile. The site links to broader Andean and Pacific networks including material paralleled in coastal and highland contexts such as the Atacama Desert, the Altiplano, and the Titicaca Basin, and has attracted research from institutions in South America, Europe, and North America.

Geography and Location

The site lies on the coastal bluff adjacent to the city of Arica, in the northern reaches of the Arica and Parinacota Region, overlooking the Pacific Ocean. It occupies a position between the hyperarid Atacama Desert margins and the lower slopes of the Andes, proximate to ancient caravan routes linking the Altiplano with littoral fishing towns referenced in chronicles of the Spanish Empire and later cartographic surveys by the Instituto Geográfico Militar (Chile). Nearby geographic references include the Lluta River valley, the port of Arica, and the coastal headlands featured in nineteenth-century travelogues by figures associated with the Royal Geographical Society.

Geology and Formation

The cavity developed within Pleistocene and Holocene coastal terrace deposits dominated by cemented sandstones, conglomerates, and volcanic tuffs correlated with regional uplift associated with the Nazca Plate–South American Plate interaction. Marine terraces at the site correspond to sequences studied in tectonic research tied to major seismic events such as the 1868 Arica earthquake and earlier megathrust ruptures recorded by paleoseismology teams affiliated with the United States Geological Survey and Chilean seismological programs. Sedimentology analyses reference comparanda from coastal outcrops near Iquique and lithostratigraphic frameworks used by the Servicio Nacional de Geología y Minería.

Archaeological Discoveries

Excavations recovered human remains, funerary bundles, textile fragments, shell middens, and stone tools akin to assemblages attributed to preceramic and early ceramic traditions documented across the southern Pacific littoral and Andean margins. Burial contexts exhibited stratigraphy comparable to finds reported from Pukara and early coastal cemeteries studied by teams from the Museo Nacional de Historia Natural (Santiago) and international collaborators from institutions such as the British Museum, the Smithsonian Institution, and the Universidad de Chile. Organic preservation enabled radiocarbon dating suites conducted at laboratories including those affiliated with the University of California, Berkeley and the Laboratoire des Sciences du Climat et de l'Environnement, producing chronologies that interface with regional sequences like the Formative and Early Horizon periods discussed in comparative studies with sites like Cerro Sechín and Pukara de Ajipa.

Human Use and Cultural Significance

The site illustrates repeated coastal occupation, mortuary practice, and craft production connected to maritime subsistence and exchange with highland polities including interactions paralleled in ethnohistoric records concerning groups later termed Aymara and pre-Aymara communities encountered by agents of the Viceroyalty of Peru. Material culture exhibits affinities with coastal fishing traditions, camelid exchange networks, and textile styles compared in dissertations from the Pontificia Universidad Católica de Chile and field reports referenced by the Instituto de Investigaciones Arqueológicas y Museo at regional museums. Cultural interpretations draw on frameworks established by scholars associated with the Society for American Archaeology and methodologies promoted at conferences of the International Council on Monuments and Sites.

Excavation History and Research

Fieldwork began in the early twentieth century with collections assembled by collectors connected to the Museo Arqueológico San Miguel de Azapa and later formal excavations by teams from the Universidad de Tarapacá, the Universidad de Chile, and international consortia including researchers from the University of Cambridge and the Max Planck Institute for the Science of Human History. Research outputs include osteological analyses published alongside comparative isotope studies conducted in laboratories such as the W. M. Keck Carbon Cycle Accelerator Mass Spectrometry Facility and artefact studies appearing in journals affiliated with the National Geographic Society and the Latin American Antiquity editorial board. The multidisciplinary record involves collaborations with conservation departments at institutions like the Museo de La Plata and doctoral projects supervised through the Universidad Nacional Autónoma de México.

Conservation and Site Management

Conservation strategies coordinate Chilean cultural heritage authorities such as the Consejo de Monumentos Nacionales with municipal bodies in Arica and university partners to mitigate looting, erosion, and development pressures documented in environmental impact assessments submitted to the Ministerio de Desarrollo Social y Familia (Chile) and planning agencies tied to the Servicio Nacional de Turismo (SERNATUR). Management practices adopt standards promulgated by the International Council on Monuments and Sites and training programs from the Getty Conservation Institute, integrating community consultation protocols modeled on participatory initiatives involving local museums like the Museo del Mar de Arica and cultural organizations linked to regional indigenous associations recognized by the Comunidad Indígena Aymara. Monitoring employs remote sensing techniques developed in projects with the National Aeronautics and Space Administration and geospatial teams from the Universidad de Chile.
