Guardians of the Andes: South America's Ice Fields and Mountain Glaciers

South America hosts one of the world's most extensive and diverse glacial systems outside of Antarctica and Greenland, containing approximately 99% of all tropical glaciers on Earth, as well as some of the largest temperate ice fields in the Southern Hemisphere. Stretching along the spine of the Andes Mountains, this remarkable glacial network encompasses nearly every type of glacial environment found on the planet. South America's glaciers are a critical component of the global cryosphere, serving as vital freshwater reservoirs for hundreds of millions of people.

Ice at the Edge of the Tropics: The Glaciers of Volcanic Mexico

Mexico has one of the world's most unique and fragile glacial systems. It contains some of the southernmost glacial ice in North America, hanging on the peaks of tall volcanoes that reach into the tropical sky. This incredible paradox—ice in a mostly tropical country—shows how extreme elevation can overpower latitude-related warming to create the right conditions for glaciers. These impressive ice formations are not only geological wonders but also key signs of climate change in one of the world's most vulnerable glacial areas.

The Archaeological Ensemble of 17th Century Port Royal: Jamaica's Sunken Colonial Capital

At Kingston Harbour in southeastern Jamaica lies the remains of Port Royal, once the most important English port in the Caribbean and the fourth largest city in the Americas. This colonial city, thriving in the late 17th century as a trade, naval, and piracy hub, was devastated in 1692 when an earthquake submerged two-thirds of its territory. The site, inscribed by UNESCO, offers rare insights into colonial urban life, maritime trade, and social dynamics, embodying a global archaeological treasure and a reminder of the power of natural disasters to reshape civilization.

The Wixárika Route through Sacred Sites to Wirikuta (Tatehuarí Huajuyé): Mexico's Sacred Pilgrimage Path

In north-central Mexico, an ancient network of sacred pathways connects mountains, deserts, and valleys, linking the spiritual heart of the Wixárika culture to their sacred site. The Wixárika Route through Sacred Sites to Wirikuta, called Tatehuarí Huajuyé in Wixárika, is a major pre-Columbian pilgrimage route still used today. Recently recognized by UNESCO, it spans five Mexican states with 20 sacred sites that form the cultural core of Wixárika civilization. More than a trail, it embodies a living cosmology where landscape, spirituality, agriculture, and community converge, maintaining a tradition over a millennium.

Cavernas do Peruaçu National Park: Exploring Brazil's Peruaçu River Canyon

In northern Minas Gerais, Brazil, the Peruaçu River Canyon, a UNESCO World Heritage Site, is encompassed by Cavernas do Peruaçu National Park. This remarkable landscape showcases geological formations, biological diversity, and human history spanning millennia. Limestone formations have created an underground world with over 140 caves and prehistoric rock art dating back 12,000 years. The canyon exemplifies the interplay of geological, natural, and cultural development that has shaped this unique corner of Brazil.

Island Sanctuaries: Vieques and Culebra National Wildlife Refuges

The wildlife refuges of Vieques and Culebra are key conservation success stories on Puerto Rico's eastern islands. The Vieques National Wildlife Refuge, on former U.S. Navy lands, covers over half the island, while the Culebra National Wildlife Refuge protects marine and coastal habitats on 23 cays and parts of Culebra's coast. Together, these refuges safeguard some of the most biodiverse and ecologically intact habitats remaining in the U.S. Caribbean, serving as sanctuaries for endangered species while supporting sustainable tourism and scientific research.

The Serranía del Baudó: Colombia's Hidden Biodiversity Sanctuary

Colombia's Pacific coast is home to one of the world's most remarkable yet least understood mountain ranges. Rising from the humid lowlands of the Chocó department, the Serranía del Baudó stands as a critical biodiversity sanctuary and a testament to the complex interplay between topography, climate, and evolution in the Neotropics. It is a recognized center of terrestrial and aquatic biodiversity, and a source of fish species for Mesoamerica. Yet, scientific exploration of this region remains remarkably limited, leaving numerous biological treasures yet to be discovered.

The Crystalline Expanse: Salinas Grandes and Argentina's High-Altitude Salt Desert

Stretching across the rugged landscape of northwestern Argentina like a frozen sea of white crystals, Salinas Grandes stands as one of South America's most spectacular natural phenomena. These vast salt flats represent the third-largest salt desert in South America and one of the most accessible high-altitude salars on the continent. The gleaming white expanse offers visitors an otherworldly experience that combines geological wonder with cultural significance, creating a destination that captivates scientists, photographers, and travelers.

Venezuela's El Ávila National Park: From Cloud Forest to Páramo

Rising majestically above Venezuela's capital city, El Ávila National Park stands as both a natural fortress and a green sanctuary that has shaped the identity of Caracas for centuries. The park encompasses the entire mountain range that serves as the northern boundary of the Caracas valley. With its towering peaks, diverse ecosystems, and rich biodiversity, El Ávila represents one of Venezuela's most accessible yet ecologically significant protected areas, offering a remarkable example of how urban development and wilderness conservation can coexist.

Sierra Nevada National Park: Venezuela's Alpine Sanctuary

Nestled within the rugged peaks of the Venezuelan Andes, Sierra Nevada National Park stands as one of South America's most significant mountain protected areas. Established in 1952, this sanctuary encompasses the highest elevations in Venezuela, protecting critical Andean ecosystems while serving as a refuge for numerous endemic species. The park's remarkable elevation range creates a natural laboratory where multiple ecological zones demonstrate the complex relationships between altitude, climate, and biodiversity.
