Lake Hillier, Pink salt lake in Recherche Archipelago, Western Australia.

This body of water measures 600 meters (1970 feet) long and 250 meters (820 feet) wide, displaying rose-colored water that contrasts sharply with the surrounding dense paperbark and eucalyptus forest and the blue waters of the Southern Ocean beyond.

Navigator Matthew Flinders recorded this feature in January 1802 during his coastal survey, naming it after crew member William Hillier who perished on Middle Island and was buried there while the expedition conducted scientific observations of the region.

Aboriginal communities knew of this body of water long before colonial settlement, understanding its place within the island ecosystems of the Recherche Archipelago and the natural features defining this remote coastal region.

Visitors can observe it through daily scenic flights from Esperance Airport, as Middle Island remains uninhabited and subject to access restrictions. Boat tours circumnavigate the island without landing, while charter flights provide optimal viewing conditions from above.

Dunaliella salina microalgae and halophilic bacteria generate the persistent coloration that remains evident even in extracted water samples. Scientists continue investigating the precise combination of organisms responsible for maintaining this unusual permanent hue throughout the year.

Geological formations: rock structures, caves, thermal springs

This collection presents geological formations created through natural processes over millions of years. From layered sandstone waves in Arizona to volcanic basalt columns in Northern Ireland, these locations demonstrate Earth's geological diversity. Erosion, tectonic activity, and mineral deposits have shaped landscapes that provide insights into our planet's history. The selection includes limestone caves in New Zealand with glowworms, thermal springs in Turkey with travertine terraces, and colored rock formations in China created by iron-rich minerals. Visitors will find glacier caves in Iceland, canyons in Utah, and salt pans in Namibia. Each location documents specific geological processes and offers opportunities to explore different rock formations and natural phenomena.

Unusual natural wonders and geological formations worldwide

This collection presents extraordinary natural phenomena and geological formations across all continents, from salt flats and volcanic crater fields to underground cave systems and landscapes shaped by mineral deposits. The featured sites display rare geological processes: moving stones leave mysterious tracks across California desert playas, methane gas feeds flames in a Turkmenistan crater for decades, and thermal springs create white travertine terraces in the Turkish countryside. Coral reefs form circular structures off the coast of Belize, while chemical reactions turn lakes pink in Australia and rivers brilliant colors in Colombia. The geological features include hexagonal basalt columns along the Northern Irish coast, conical limestone hills on Philippine islands, and mushroom shaped sandstone formations in Utah. Caves in New Zealand house thousands of bioluminescent larvae, while one of the world's largest caverns lies beneath Vietnamese mountains. Locations range from a geyser studded desert basin in Nevada to red algae carpets along Chinese shores to isolated islands off the Yemeni coast with endemic flora. This collection encompasses both ancient archaeological puzzles like stone jars in Laos and ground drawings in Peru, as well as natural optical illusions such as apparent underwater cascades off Mauritius.

Discover hidden treasures of the world

This collection leads to places that remain outside standard tourist circuits. The selection includes natural landscapes and cultural sites that receive limited attention from international visitors. From the salt flats of Bolivia to ancient ruins in Turkish mountain terrain and the ice formations of Lake Baikal, the collection provides access to less frequented regions. Natural phenomena include the Benagil Cave along Portugal's Algarve coast, the Great Blue Hole off Belize, and the sandstone formations of The Wave in Arizona. Cultural sites such as Quinta da Regaleira near Lisbon, the abandoned nitrate town of Humberstone in Chile, and the fortified Berber village of Ait Benhaddou in Morocco show historical building methods and past ways of life. The Meteora monasteries in Greece and the Waitomo glowworm caves in New Zealand demonstrate the connection between human settlement and natural environment. The locations span all continents and climate zones. They range from tropical regions like the turquoise river at Hinatuan in the Philippines, through temperate zones like the Cinchado rock formation on Tenerife, to remote areas such as Pangong Lake in Indian Ladakh and the limestone pinnacles of Tsingy de Bemaraha in Madagascar. The collection allows travelers to experience regional characteristics without commercial tourism infrastructure.

Satellite images reveal remote places on earth

The satellite imagery displays natural formations, artificial islands, and historical sites. The photographs document geological structures like the Richat crater in Mauritania and the Badlands Guardian in Canada. Views include Palm Jumeirah in Dubai, Nazca Lines in Peru, and El Castillo in Mexico.
