The Mystery of the Skeletons of Roopkund Lake

Researchers have debated various theories regarding the mysterious skeletons found in the Roopkund Lake, each with its own rationale based on historical context and available evidence.

Soldiers from India or Japan were killed while trying to invade Tibet

During World War II, when India was still under British rule and fears of a Japanese invasion loomed, one of the first theories suggested that the skeletons may belong to soldiers from India or Japan. A specific campaign between May and June of 1841 was mentioned, where Indian soldiers attempting to invade or flee Tibet were repelled, tried to escape, and then possibly perished due to a storm near the lake. However, the Japanese soldiers' theory was ruled out when it was established that a British climber had sighted the skeletons years before, in 1907.

No weapons found at the site

Further examination revealed that no weapons were recovered at the lake except for a single spearhead, undermining the soldier theory.

The skeletons were Tibetan traders or local villagers who died of an epidemic

With soldier-related theories becoming less credible because of the lack of weaponry, researchers considered that the skeletons might be Tibetan traders on the Silk Road, another trade route, or local villagers who died from an epidemic. The idea was that victims of disease were removed from populated areas for disposal.

Lack of evidence of trade route and local trade

However, this trader theory was also dismissed due to the absence of any traces of a trade route and the impractical locale for traders.

The skeletons were from a ritual suicide site

A recent scientific analysis reveals surprising findings about the diverse origins and timelines of skeletal remains.

Genetic testing revealed the skeletons belonged to three distinct genetic groups

The skeletons investigated in the study belonged to three different genetic backgrounds, which counters the previous assumption of a singular catastrophic event leading to mass fatalities.

23 skeletons had South Asian ancestry, 14 had Mediterranean ancestry, and 1 had East Asian ancestry

Specifically, 23 skeletons were identified to have a gene pool corresponding to South Asian ancestry. Fourteen others bore no genetic resemblance to South Asians but instead appeared to originate from Mediterranean regions. Furthermore, one individual was determined to belong to a third group with East Asian ancestry, possibly Han Chinese.

This diversity in origins contradicted the idea of a single mass death event

The genetic diversity suggests multiple distinct events or migrations led to these individuals' demise at the site, challenging the earlier notion of a single mass death event.

Diet analysis of the skeletons matched their genetic ancestry

Investigative findings on the dietary preferences of the skeletal remains were consistent with their genetic backgrounds, which further supported the genetic evidence.

The Mediterranean group had a diet of wheat, barley and rice, while the South Asian group ate millet

The analysis showed the group with Mediterranean ancestry primarily consumed wheat, barley, and rice. In contrast, the diet of individuals with South Asian ancestry indicated a significant consumption of millet.

This supported the genetic findings and showed the groups were distinct

The correlation between diet and genetic background underpinned the distinctiveness of the groups, suggesting they were indeed separate people from different regions.

Radiocarbon dating showed the skeletons spanned a 1,000-year period

Radiocarbon dating of the remains revealed a surprising chronological range, indicating the skeletons did not die simultaneously but over an extensive timeframe.

The South Asian group died between the ...

The mystery surrounding an ancient site has persisted, largely due to the disturbances and difficulties in research efforts.

Lack of context due to disturbance of the site

The original context of the site has been severely disrupted as hikers and commercial climbers have rearranged and removed bones. Over the decades, they've not only taken bones but also looted artifacts, which further complicates the efforts of researchers trying to solve the mystery. This theft and tampering have stripped away vital contextual clues that could have led to a greater understanding of the site.

Potential for more discoveries from the lake itself

Despite the challenges, there remains potential for new discoveries. The lake, being frozen most of the year, has preserved many more skeletons that could be analyzed. These skeletons are from an estimated 800 individuals at the lake, and as more are examined, they could yield new data that might shed light on the mysteries of the site.
