High in the Indian Himalayas, at an altitude of 5,029 metres, lies a small glacial tarn that has baffled explorers, scientists, and trekkers for nearly a century. Known as Roopkund or more famously as Skeleton Lake, this icy pool in Uttarakhand’s Chamoli district is strewn with hundreds of ancient human skeletons.
Despite decades of scientific research, folklore, and speculation, the lake continues to pose more questions than answers about who these people were, when they died, and how they came to rest in such a desolate, high-altitude valley.
In 1942, a British forest ranger named H K Madhwal stumbled upon a macabre sight: hundreds of skeletons lying around and beneath the frozen waters of Roopkund. Estimates suggest that between 300 and 800 individuals met their fate here. The dry, cold air of the Himalayas preserved bones, flesh, hair, and even wooden artefacts.
The bizarre find was made public in the late 1950s, sparking a wave of investigations and theories that continue to this day.
Initially, it was thought the remains belonged to Japanese soldiers attempting to enter India during World War II. Others suggested Tibetan traders or victims of an epidemic.
A more compelling theory emerged in 2004, when forensic studies revealed that many skulls bore blunt force trauma consistent with giant hailstones. Researchers concluded that the dead were likely pilgrims on the once-in-12-years Nanda Devi Raj Jat Yatra, a revered Hindu pilgrimage that still passes near Roopkund on the way to Homkund.
The remains, including men, women, and porters, seemed to belong to a group caught in a catastrophic hailstorm around the 9th Century. Musical instruments and folklore about goddess Nanda Devi’s wrath killing irreverent pilgrims bolstered the theory.
Over time, Roopkund evolved from being an archaeological curiosity into one of India’s most iconic trekking routes. The 50km trail begins in quiet Himalayan villages, winds through dense oak forests and vast alpine meadows known as bugyals, and climbs up to the icy Junargali ridge at 5,000m, where trekkers are rewarded with sweeping views of Himalayan peaks. For nearly a decade, this route became the centrepiece of India’s adventure tourism boom. But its popularity came at a cost—overuse and environmental damage eventually forced the government to ban camping in the fragile bugyals, rendering the once-celebrated trek inaccessible.
Just when it seemed that the mystery of Skeleton Lake was nearing resolution, scientific advances reopened the debate. In 2019, results of a five-year global study startled researchers. DNA analysis of 38 skeletons revealed three distinct groups: one of South Asian origin, dating between the 7th and 10th Centuries; another of eastern Mediterranean ancestry, linked to Crete, who died in a single event in the 19th Century; and one individual of Southeast Asian origin, also from the 19th Century. These findings dismantled the earlier theory of a single catastrophic event, instead suggesting that Roopkund had been the site of multiple episodes over more than a millennium.
The revelations deepened the enigma. How did people of Mediterranean descent end up in such a remote Himalayan landscape? Were they travellers, settlers, or descendants of an ancient isolated population? And why did distinct groups perish here, centuries apart? While theories range from hailstorms and fatal falls from Junargali to acute mountain sickness, none fully explain the scale or diversity of the remains.
Archaeologists such as Veena Mushrif-Tripathy urge caution in declaring the puzzle solved. Only a few skulls show signs of hail injuries, and years of trekking activity have disturbed the site—some bones even carried away as souvenirs—making clear interpretation increasingly difficult.
Today, Roopkund remains frozen for most of the year, its eerie trove of skeletons emerging only when the snow melts. Promoted in tourism campaigns as a “mystery lake,” it continues to defy conclusive answers. With hundreds of bodies still unstudied, scientists believe more surprises may lie hidden in this icy grave. For now, the lake of skeletons endure in the shadow of Trisul peak, holding fast to its secrets while captivating trekkers, researchers, and storytellers alike.

1. Where is Skeleton Lake located?
Roopkund, or Skeleton Lake, lies at an altitude of about 5,029 metres (16,500 ft) in the Chamoli district of Uttarakhand, India. It sits in a glacial hollow beneath the slopes of Trisul, one of the state’s highest peaks.
2. Why is it called Skeleton Lake?
The lake earned its eerie nickname after hundreds of human skeletons were discovered here in 1942. Depending on the season, bones and skulls become visible when the ice melts.
3. How many skeletons are at Roopkund Lake?
Estimates suggest there are between 300 and 800 skeletons scattered in and around the lake, dating from as early as the 7th Century to as late as the 19th Century.
4. Can tourists visit Roopkund today?
The once-popular Roopkund trek is currently banned due to concerns about environmental damage to fragile alpine meadows (bugyals). Trekkers cannot camp in the area, though scientific studies may still access the site.
5. Why is Skeleton Lake famous?
Skeleton Lake remains one of the world’s greatest archaeological mysteries. DNA studies show the skeletons belong to genetically diverse groups, including South Asians, Southeast Asians, and even people of Mediterranean ancestry, making its history even more intriguing.
