Dargan Shelter: Unearthing Ice Age Aboriginal Life in the Blue Mountains
Key Concepts:
- Dargan Shelter: A sandstone cave in the Upper Blue Mountains, Australia.
- Radiocarbon dating: A method used to determine the age of organic materials.
- Artifacts: Objects made or modified by humans, typically of archaeological or historical interest.
- Dreaming track/Song track: Aboriginal pathways of cultural and spiritual significance.
- Ice Age: A period of long-term reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.
Discovery and Significance of Dargan Shelter
The video explores the archaeological significance of Dargan Shelter, a sandstone cave located in the Upper Blue Mountains outside Sydney, Australia, at an elevation of 1,111 meters. The journey to the cave is described as part of the experience, leading to a "big cathedral" with rock art, including faded hand stencils. The cave is approximately 25 meters high, 22 meters wide, and 20 meters deep.
Challenging Previous Assumptions
Previously, scientists questioned whether the Blue Mountains landscape, at such high elevations, was too treacherous for human habitation during the Ice Age. However, discoveries within Dargan Shelter have challenged this assumption.
Archaeological Excavations and Findings
Three archaeological digs at Dargan Shelter yielded 693 ancient artifacts and cultural objects. These finds provide a "full sequence of occupation" dating back to the last Ice Age, potentially even earlier. The oldest object discovered was dated to 20,000 years ago using radiocarbon dating on a fireplace.
Significant Artifacts and Their Uses
Two particularly significant finds are highlighted:
- Iron-infused Sandstone Slab: This slab features linear grooves, indicating it was used for sharpening bone or wood into points. Dr. Amy Weey suggests it may have been used to create needles for sewing clothes during the cold climate, dating back 13,500 years to the end of the last Ice Age.
- Basalt Stone: This stone is believed to have been used for cracking seeds or nuts. The impact marks on the stone provide evidence of this activity, allowing archaeologists to reconstruct the diet of the inhabitants.
Implications for Understanding Aboriginal History
These findings provide evidence that Aboriginal people lived in the Blue Mountains for over 30,000 years and traveled at high elevations, challenging previous assumptions about their movements and capabilities during the Ice Age.
Cultural Significance and Dreaming Tracks
The area surrounding Dargan Shelter is culturally significant as it lies on a "dreaming track" or "song track." This track connected various Aboriginal groups from the north, east, west, and south, leading to major ceremonial grounds in the high country.
Environmental Challenges and Adaptation
The video acknowledges the harsh environmental conditions during the Ice Age, including a lower tree line and limited food sources. The inhabitants of Dargan Shelter would have faced challenges in obtaining firewood and sustenance.
Weaving Narratives and Connecting Science and Culture
The video emphasizes the importance of "weaving narratives" from the stories found in the stone, highlighting the collaboration between science and culture in archaeology.
Custodial Connection and Healing
Erin Wilkins, a direct custodian, expresses a deep connection to the land and ancestors, emphasizing the healing power of returning to these sites. The findings at Dargan Shelter provide clarity, information, and a deeper understanding of Aboriginal history and culture.
Touchstones for History and Relationships
The video concludes by emphasizing that these sites are not merely "dots on the map" but "touchstones for history," representing relationships with the land and law that are deeper than can be imagined.
Synthesis/Conclusion
Dargan Shelter is a significant archaeological site that has reshaped our understanding of Aboriginal life in the Blue Mountains during the Ice Age. The artifacts discovered provide tangible evidence of their presence, activities, and adaptations to a challenging environment. The site's cultural significance as part of a dreaming track further underscores its importance in Aboriginal history and spirituality. The research highlights the power of archaeology to connect science and culture, weaving narratives that deepen our understanding of the past and its connection to the present.
