Archaeologists Discover Human Remains in Forgotten ‘Desert Refuge’ Lava Tubes!

Archaeologists have made a fascinating discovery in the Umm Jirsan lava tube system in northwest Saudi Arabia, unearthing human remains and other relics that reveal the lives of ancient people who lived in one of the world’s most arid regions.

The Umm Jirsan lava tubes, created by ancient volcanic activity, have long been an overlooked part of Arabia’s archaeological history. However, a recent study led by Griffith University has now provided a detailed look into the lives of early human populations who used these caves for shelter, often traveling between oases and pastoral lands.

Lava Tubes: The Desert’s Secret Cool Hangout

Lava tubes in arid environments are rare preservation sites. According to Matthew Stewart, lead researcher at Griffith University, the Umm Jirsan tunnels likely served as temporary shelters during travels between oases. The caves, which stretch nearly a mile long with ceilings as high as 39 feet, provided a safe haven for both people and their livestock.

“Our findings at Umm Jirsan provide a rare glimpse into the lives of ancient peoples in Arabia, revealing repeated phases of human occupation and shedding light on the pastoralist activities that once thrived in this landscape,” Stewart said.

The discovery of remains, pottery, and other artifacts shows how the lava tubes functioned as crucial waypoints for ancient travelers.

Livestock & Humans: A Timeless Bond

Coupled with human remains, archaeologists uncovered numerous animal bones, including those of cattle, goats, and sheep, which were likely kept inside the caves for shelter. Published in PLOS One, this discovery confirms the pastoral nature of the lifestyle of the region’s early inhabitants. Rock art found at the site depicts these same animals, helping researchers understand the types of livestock that were integral to these ancient communities.

The evidence of animals in the caves shows that the lava tubes were also used by livestock, giving us a glimpse into the pastoral lifestyle of the time. These caves provided shelter for both people and animals, with the animals grazing on wild plants around the area, helping the herders during their long desert journeys.

Tracking the Paths of Early Desert Nomads

The research surrounding the Umm Jirsan lava tubes offers a rare look at the movements and lifestyles of ancient peoples between the Stone and Bronze Ages. With human remains ranging from 150 years ago to 6,000 years ago, the site has revealed a pattern of recurrent use over millennia.

The discovery of animal bones and pottery, along with the rock art, helps piece together the story of a culture that relied heavily on livestock and trade. Professor Michael Petraglia, another member of the research team, emphasized the importance of these findings:

“These findings underscore the immense potential for interdisciplinary investigations in caves and lava tubes,” Petraglia said in a statement, “offering a unique window into Arabia’s ancient past.”

The data collected from the site reveals how people adapted to and thrived in one of the world’s most inhospitable environments.
