Laguna de Guayatayoc is a high‑altitude saline lake in the Puna de Atacama of northwestern Argentina, situated within Jujuy Province near the border with Salta Province and the Salar de Pocitos region. The lake lies on the altiplano between the Andes volcanic cordillera and the Sierra de Cachi foothills, forming part of a chain of endorheic basins that includes the Laguna de Pozuelos and Salar de Jama. It is seasonally variable in extent and ecologically linked to surrounding wetlands and salt flats documented in regional studies by institutions such as the National Scientific and Technical Research Council (Argentina) and the Universidad Nacional de Jujuy.
Laguna de Guayatayoc occupies a depression on the Altiplano, south of the Abra Pampa corridor and north of the Río Grande de Jujuy watershed, proximate to routes connecting San Salvador de Jujuy and Susques. The lake is set among volcanic and metamorphic terrains associated with the Central Volcanic Zone and adjacent to geomorphological features like the Quebrada de Humahuaca and the Salar del Hombre Muerto basin. Administratively it falls within the Yavi Department and influences nearby localities including La Quiaca and Santa Catalina.
As an endorheic saline water body Laguna de Guayatayoc receives inflow from intermittent high‑Andean tributaries draining the Cordillera Occidental and from seasonal precipitation influenced by the South American Monsoon System and the El Niño–Southern Oscillation. Evaporation rates driven by high insolation, low humidity and strong winds typical of the Puna cause marked interannual variability, with surface area fluctuating between ephemeral ponding and broader shallow lakes, similar to dynamics observed at Laguna Pozuelos and Salar de Atacama. The lake’s chemistry reflects inputs from volcanic rocks and evaporative concentration, producing elevated salinity and mineral assemblages akin to those recorded by geochemical surveys from the Instituto Geográfico Nacional (Argentina).
The lake and its peripheral wetlands provide habitat for migratory and resident species characteristic of high‑Andean ecosystems, including several flamingo taxa such as the James's flamingo, the Andean flamingo and the Chilean flamingo, along with waterfowl recorded in inventories by the Aves Argentinas and the Wetlands International datasets. Submerged and emergent saline‑tolerant vegetation supports invertebrate communities dominated by brine shrimp and halophytic microfauna analogous to those documented in Salar de Uyuni studies, sustaining breeding colonies for birds and foraging areas for camelids like vicuña and domestic llama and alpaca managed by local populations. The lake’s biota is influenced by altitude‑adapted predators including the Andean fox and raptors such as the Andean condor, with ecological interactions comparable to conservation assessments performed at Reserva de Biosfera de la puna sites.
Human presence around Laguna de Guayatayoc links to traditional pastoralism practiced by indigenous communities including groups connected to historical polities such as the Inca Empire and modern municipalities administered through provincial councils in Jujuy Province. Local livelihoods rely on extensive grazing of camelids, artisanal salt extraction, and small‑scale agriculture in irrigated valleys influenced by the lake’s hydrological cycle, as reflected in socioeconomic reports by the Ministerio de Desarrollo Social (Argentina) and regional NGOs. The area also features nascent nature‑based tourism tied to birdwatching and cultural heritage trails promoted by provincial tourism authorities in Argentina and by organizations involved in Andean archaeology and community‑based enterprises around sites like Humahuaca and Pucará de Tilcara.
Laguna de Guayatayoc lies within a landscape with archaeological records of prehispanic occupation, caravan routes linking the Altiplano to lowland markets used during the Formative Period (Andes) and subsequent incorporation into the Inca road system (Qhapaq Ñan). Ethnohistoric sources and contemporary oral traditions of communities such as those associated with Jujuy Province reference ritual use of lake margins and salt resources, echoing practices described in colonial chronicles held in Argentina’s national archives and museums like the Museo de Arte Hispanoamericano Isaac Fernández Blanco. The lake features in regional cultural festivals and in the intangible heritage recognized by provincial cultural directorates, paralleling rites maintained in towns such as Humahuaca and Tilcara.
Conservation concerns for Laguna de Guayatayoc reflect pressures from water extraction, grazing intensity, mineral prospecting, and climate change impacts documented in regional vulnerability assessments by the National University of Salta and the Comisión Nacional de Actividades Espaciales (CONAE), which monitor hydrological variability via remote sensing. Protected‑area designations in nearby sectors, such as Reserva Provincial Laguna de los Pozuelos and other Área Natural Protegida initiatives, provide management models but the lake lacks extensive formal protection; environmental NGOs and research institutions including Conservación Internacional and the Fundación Biodiversidad Argentina have advocated integrated conservation strategies. Key issues include maintenance of flamingo breeding habitat, control of invasive species, regulation of extractive projects, and community‑led stewardship measures coordinated with provincial authorities and international frameworks like the Convention on Wetlands of International Importance (Ramsar).
