Three Sisters Rock Formations, Blue Mountains

The Three Sisters are three towering sandstone rock pillars rising approximately 922, 918, and 906 meters above sea level respectively, located near Katoomba in the Blue Mountains of New South Wales. These distinctive formations stand as sentinels overlooking the Jamison Valley, their weathered faces carved by millions of years of erosion from the ancient Jamison Creek. The pillars are composed of Triassic period sandstone, estimated to be around 200 million years old, and represent some of the most photographed landmarks in Australia. For the Gundungurra and Darug peoples, these formations hold profound spiritual significance, serving as a focal point for Dreamtime stories that have been passed down through countless generations. Some proponents of ancient astronaut theory have proposed that the Blue Mountains region, including the Three Sisters, represents a site of ongoing extraterrestrial contact, citing indigenous accounts of encounters with unusual beings and reported UFO sightings in the area since the mid-20th century. Geologists and archaeologists explain the Three Sisters formation through well-documented processes of differential erosion acting on Triassic sandstone over millions of years, while the rich body of Dreamtime narratives associated with the site reflects the deep cultural and spiritual knowledge systems of the Gundungurra and Darug peoples. The convergence of Indigenous tradition, natural geological processes, and modern UFO reports continues to make the Three Sisters a focal point for discussions bridging archaeology, geology, and contemporary claims about extraterrestrial visitation.

What the Show Claims
- ›The Blue Mountains, including the Three Sisters formation, are an active site of contact between indigenous Australians and Pleiadian extraterrestrialsS15E07
- ›Aboriginal elders report encounters with 'tall blue beings' in the areaS15E07
- ›The region has been a UFO hot spot since the 1950s with numerous sightings reportedS15E07
Theorist Takes
“There are definitely stories of Pleiadians in contact through the whole of that region, Blue Mountains and Gosford. It is where they've come down and worked with them. I've been with elders who swear to this day they have spoken to tall blue beings, and they've given information to them.”
From the Transcripts
“According to the indigenous population, distinctive rock formations in the Blue Mountains called the Three Sisters are what remains of seven stone spires that once stood here. Locals associate them with the seven visible stars of the Pleiades.”
What Archaeology Says
The Three Sisters represent a fascinating intersection of geological processes and cultural preservation rather than traditional archaeological excavation sites. The formations themselves are natural sandstone pillars carved by erosion over millions of years, but the surrounding area contains significant Aboriginal cultural sites including rock art, tool-making sites, and ceremonial grounds that archaeologists have studied extensively.
Researchers working in the broader Blue Mountains region have documented extensive evidence of long-term Aboriginal occupation, including stone tool workshops, shelter sites with cultural deposits, and rock art galleries that provide insights into the spiritual and practical lives of the Gundungurra and Darug peoples. The area's cultural landscape has been mapped through collaborative projects between archaeologists and local Aboriginal communities.
The scientific consensus views the Three Sisters as a textbook example of differential erosion, where harder sandstone caps have protected the underlying rock while softer surrounding material has been worn away. Geologists have studied the formations to understand broader patterns of landscape evolution in the Blue Mountains, which themselves represent an uplifted plateau dissected by river systems over millions of years.
What remains genuinely intriguing is the depth of Aboriginal oral traditions associated with the site, including detailed Dreamtime stories that some researchers suggest may contain encoded information about ancient environmental changes or geological events. The challenge lies in bridging indigenous knowledge systems with Western scientific approaches to fully understand the cultural and natural heritage of this remarkable landscape.
Mysteries & Fun Facts
The Three Sisters are named Meehni, Wimlah, and Gunnedoo according to local Aboriginal legend
The formations change color throughout the day, appearing golden at sunrise and deep red at sunset due to iron oxide in the sandstone
The Giant Stairway carved into the cliff face contains over 800 steps leading down into the valley
The Blue Mountains get their blue appearance from eucalyptus oil vapor in the atmosphere creating a distinctive haze
Planning a Visit
The Three Sisters are easily accessible via the Three Sisters Lookout in Katoomba, with paved walking paths and viewing platforms suitable for all ages. The Echo Point visitor center provides interpretive displays about both the geological formation and Aboriginal cultural significance, while the Giant Stairway allows more adventurous visitors to descend partway into the Jamison Valley.
Sydney, approximately 100 kilometers southeast
Winter months (June-August) often provide the clearest views with crisp air and minimal haze, though the site is spectacular year-round. Early morning visits typically offer the best photographic conditions and fewer crowds.
