Explorers have discovered a pool in a deep cave in a US park. Pictures show the "wondrous" blue pool - never before been seen by human eyes - that was found in the depths of Carlsbad Caverns National Park in New Mexico, USA.

The alien-like pool contains milky aquamarine liquid, surrounded by white frosted rock, the Kansas City Star reports. According to the Daily Mirror, it is believed that the cave has evolved over thousands of years and has been completely untouched by humans.

Rodney Horrocks, chief of natural and cultural resources at Carlsbad Caverns National Park, said "This pool has been isolated for hundreds of thousands of years and had never seen light before that day."

The eerie discovery was made 700ft below the entrance of Lechuguilla Cave, one of the 10 longest caves in the world. Although it was discovered in 1993, explorers only entered its "virgin" passages for the first time in October.

Posting news of the discovery on Facebook, geoscientist Max Wisshak said: "Exploration in caves sometimes yields wondrous sights. This cave pool, found in Lechuguilla Cave, appears to be completely pristine."

"The edges beneath this pool appear to be pool fingers, which could be bacterial colonies that have evolved entirely without human presence," he added. The expedition, led by Wisshak, involved mapping out 1.3 miles of passages and multiple rope drops. It is not known when the cave network was formed.

NEOM Nature Reserve Reintroduces Six Animal Species

As part of its bold rewilding strategy, NEOM has reintroduced more than 1,100 animals across six species to its expansive Nature Reserve—an important milestone in its broader mission to restore the region’s natural balance. With 95% of the region’s land preserved for nature, NEOM is working to rebuild self-sustaining ecosystems through habitat rehabilitation, species recovery, and cutting-edge ecological monitoring.

According to NEOM, when the Arabian Oryx was first reintroduced into the Nature Reserve in December 2022, it marked a milestone occasion, signifying the first time the animal had walked the sands of north-western Saudi Arabia for nearly 100 years, SPA reported.

In the early 1970s, the Oryx was extinct in the wild due to hunting and poaching, but conservation efforts across the region have seen its numbers swell in recent years, with more than 208 now calling NEOM home. Perfectly adapted to the region’s desert conditions, its white coat reflects the sun, while its complex nasal system cools the air it breathes and conserves water by recycling moisture as it exhales.

Another member of the Bovidae family, Arabian Sand Gazelles are petite, graceful animals that typically reside in sand dunes and coastal flats across the Arabian Peninsula. Gazelles are swift creatures, clocking speeds of up to 100 kilometers per hour in short bursts.

They are herbivores, and while NEOM’s regreening initiative continues to develop – with 4.7 million trees, shrubs, and grasses planted to date – the 530 Arabian Sand Gazelles currently residing in the reserve benefit from the natural vegetation that has returned to the area, following the removal of heavy livestock grazing. NEOM is also home to 223 Arabian Gazelles, which are typically darker in color and harder to find, preferring to reside in foothills and rugged mountain terrain.

Desert-dwelling wild goats can be found in NEOM’s rocky, mountainous terrain, and are typically recognized by their impressive arched horns. Males have backward-arched horns that can reach up to one meter in length, while females have much shorter horns and are lighter in color.

They are incredible climbers and have hooves with rubbery soles to act as suction cups on hard surfaces, aiding them in navigating steep cliffs to avoid predators, including wolves. NEOM has successfully reintroduced 53 Nubian Ibex to the reserve, adding to the population of several wild Ibex who have naturally returned to the area and are often caught on camera as part of NEOM’s monitoring program.

The red-necked ostrich, the largest and fastest living bird on earth, can stand up to 2.7 meters tall and weigh more than 150 kilograms. Their eggs are the largest of any living animal, measuring up to 15 centimeters long and up to 1.4 kilograms in weight. The bird gets its namesake from the fact that males have a reddish hue on their neck, especially in breeding season, when they perform an elaborate courtship display to attract females.

Currently, 27 chicks have been raised in NEOM Nature Reserve, which are well adapted to the region’s climate and feed on seeds, grass, leaves, and occasionally small insects or animals. Their strong legs allow them to run up to 70 kilometers per hour and, despite their size, red-necked ostriches are flightless.

Furthermore, the Lanner Falcon, last spotted in the wild in Saudi Arabia more than four decades ago, was reintroduced to NEOM Nature Reserve earlier this year in a momentous occasion. Known for its speed and agility, the Lanner Falcon can dive at speeds of more than 320 kilometers per hour. It has a striking appearance, with dark markings on its chest and belly, and a distinctive black moustache mark across its white face.

The release of Lanner Falcons into Bajdah at NEOM Nature Reserve forms part of a rewilding partnership between NEOM and the Saudi Falcon Club (SFC), which aims to reintroduce native falcon species within the Kingdom.
