Impact Craters in Aboriginal Dreamings, Part 2: Tnorala

In the previous post, I discussed Arrernte oral traditions relating to the Henbury crater field in the Central Desert.  As I said, Henbury is not the only impact crater in Arrernte country with an associated Dreaming.  Let us now travel 175 km west of Alice Springs, where we see 5 km-wide ring-shaped mountain range that stands 150 metres above the desert, representing the remnant central uplift of an eroded 22 km-wide complex crater (Figure 1).  The scientific explanation is that this structure formed from a comet impact some 142.5±0.8 million years ago.  The Western Arrente call this place Tnorala and consider it sacred.  Arrernte Elder Mavis Malbunka (Figure 2), wife of Herman Malbunka, the Traditional Custodian of Tnorala from Ntaria (Hermannsburg), explains the origin of Tnorala in Arrernte traditions and its importance today:

In the Dreaming, a group of sky-women danced as stars in the Milky Way.  One of the women, who was carrying a baby, grew tired and placed her baby in a wooden basket, called a turna or coolamon. As the women continued dancing, the turna fell and the baby plunged into the earth. The baby struck the earth and was covered by the turna, the force of which drove the rocks upward, forming the circular mountain range we see today. The baby's mother, the evening star, and father, the morning star, continue to search for their baby to this day.  She continues:

"We tell the children don't look at the evening star or the morning star, they will make you sick because these two stars are still looking for their little baby that they lost during the dance up there in the sky, the way our women are still dancing. That coolamon, the one the baby fell out of, is still there. It shows up every winter."  The coolamon (Figure 3) is the constellation Corona Australis, the Southern Crown.

Mavis warns visitors to "Be careful at night. These two stars are looking for their child, Tnorala." Still today, that evening star comes at night with big lights. The white man call it Min Min light, but we know it as the bright light of the mother looking for her child”.  

The famous Min-Min lights, which are an unexplained atmospheric phenomenon or probably an optical illusion, are frequently reputed to be the baby’s parents. "We were chased by a bright light, and the old man, my husband, realised what it was and told them that it's from the Dreamtime and it's still looking for the child. The mother must have thought that she had found her little child. Then we saw the star go up to the heavens”.  Although they are identified as the “morning star” and “evening star”, they are not explicitly identified as Venus.  Mavis notes “that was the last we saw of it, but with this big summer, we might get to see the two stars again. They don't show themselves all the time. No! Only every now and then.”

There is a long history to Tnorala that goes well beyond the stars. Cosmic impacts, murders and land rights are a component of Tnorala’s turbulent past.   To learn more, watch the full video, which you can purchase from the CAAMA.

That coolamon, the one the baby fell out of, is still there. It shows up every winter."  The coolamon (Figure 3) may actually be the "galactic bulge" - the largest and brightest region of the Milky Way, which represents the center of our galaxy and looks similar in shape to a turna or coolamon. It is seen in the region bordering Sagittarius and Scorpius and is prominent in the winter night skies (see Figure 4). The motif of the dancing stars (women) may be attributed to the Phi Sagittariids, a meteor shower that radiates from the center of the galactic bulge between 1 June and 15 July, when the Milky Way is high in the winter night sky (although this is speculative).

What we see today as the mountain range is the result of differential erosion, meaning the shocked stone is denser and eroded less than the surrounding landscape.

How ancient Aboriginal star maps have shaped Australia’s highway network

Originally published in The Conversation (Australia) on April 7, 2016 6.07am AEST
The next time you’re driving down a country road in outback Australia, consider there’s a good chance that very route was originally mapped out by Aboriginal people perhaps thousands of years before Europeans came to Australia.
And like today, they turned to the skies to aid their navigation. Except instead of using a GPS network, they used the stars above to help guide their travels.
Aboriginal people have rich astronomical traditions, but we know relatively little about their navigational abilities.
We do know that there was a very well established and extensive network of trade routes in operation before 1788. These were used by Aboriginal people for trading in goods and stories, and the trade routes covered vast distances across the Australian continent.

Star maps

I was researching the astronomical knowledge of the Euahlayi and Kamilaroi Aboriginal peoples of northwest New South Wales in 2013 when I became aware of “star maps” as a means of teaching navigation outside of one’s own local country.
My teacher of this knowledge was Ghillar Michael Anderson, a Euahlayi Culture Man from Goodooga, near the Queensland border. This is where the western plains and the star-filled night sky meet in a seamless and profound display.

One night, sitting under those stars in Goodooga, Michael pointed out a pattern of stars to the southeast, and said that they were used to teach Euahlayi travellers how to navigate outside their own country during the summer travel season.
As an astronomer, I immediately realised that those stars were not in the direction of travel that Michael was describing. And anyway, they wouldn’t be visible in the summer, let alone during the day when people would have been travelling.
Michael said that they weren’t used as a map as such, but were used as a memory aid. And in the Aboriginal manner of teaching, he asked me to research this and come back to see if “I had gotten it”.
I did some research, and looked at a route from Goodooga to the Bunya Mountains northwest of Brisbane, where an Aboriginal Bunya nut festival was held every three years until disrupted by European invasion.
It turned out the pattern of stars showed the “waypoints” on the route. These waypoints were usually waterholes or turning places on the landscape. These waypoints were used in a very similar way to navigating with a GPS, where waypoints are also used as stopping or turning points.

Stars to songlines

Further discussion revealed the reasons and methods of this technique. In the winter camp, when the summer travel was being planned in August or September, a person who had travelled the intended route was tasked with teaching others, who had not made this journey, how to navigate to the intended destination.
The pattern of stars (the “star map”) was used as a memory aid in teaching the route and the waypoints to the destination. After more research I asked Michael if the method of teaching and memorising was by song, as I was aware that songs are known to be an effective way of memorising a sequence in the oral transmission of knowledge.
Michael said, “you got it!”, and I then understood that the very process of creating, then teaching, such a route resulted in what is known as a songline. A songline is a story that travels over the landscape, which is then imprinted with the song (Aboriginal people will say that the landscape imprints the song).
I then learned that there were many routes/songlines from Goodooga to destinations as far as 700km away, which might end up in a ceremonial place, or possibly a trade “fair”.
One such route to Quilpie, in Queensland, led to a ceremonial place where Arrernte people from north of Alice Springs met the Euahlayi for joint ceremonies.
Their route of travel was more than 1,500km, crossing the Simpson Desert in summer, and I was told that they would have their own star map/songline for learning that route. The implication of this is that the use of star maps for teaching travel may have been common across Australia.

Parallels

Another surprising result of this knowledge came about when I was looking at the star map routes from Goodooga to the Bunya Mountains and Carnarvon Gorge in Queensland. When the star map routes were overlaid over the modern road map, there was a significant overlap with major roads in use today.
After some reflection, the reason for this became clear. The first explorers in this region, such as Thomas Mitchell, who explored here in 1845-1846, used Aboriginal people as guides and interpreters, who were likely given directions by local Aborigines.

These directions would no doubt reflect the easiest routes to traverse, and these were probably routes already established as songlines. Drovers and settlers coming into the region would have used the same routes, and eventually these became tracks and finally highways.
In a sense, the Aboriginal people of Australia had a big part in the layout of the modern Australian road network. And in some cases, such as the Kamilaroi Highway running from the Hunter Valley to Bourke in NSW, this has been recognised in the name.
