Between a rock and a hilly place

This appears to be a pile of rocks. It sits on top of a hill, in Glenthorne National Park, South Australia. It was not known about until very recently, when a worker involved in the development of trails stumbled upon it, in the tall grass.

The worker’s colleagues all said it was probably just nothing, but he said he had a funny feeling it was significant:

• From the hill, you can see many fields, and the ocean in the distance; it is a peaceful view.

• The rocks were clearly not from around the National Park. Some were rounded, which only happens to rocks that have been made smooth by the ocean

• The placement of the rocks looked very intentional, with some edges interlocking, not unlike a jigsaw puzzle. This suggests that they were all hand placed.

The deliberate placement of this pile of rocks lead the gentleman to conclude that this was likely a grave.


The construction workers eventually agreed to fence the rocks off out of respect.

This remains unconfirmed, but likely. In discussions with the head Archaeologist on our team, I gathered that they thought it probably was not a human’s grave, as:

• The present-day National Park was owned by very important, influential colonialists in the 19th Century, and people who died would have had Christian burials down by the Church.

• Non-Christian persons around at the time would have been Aboriginal Australian, who do not like to have hard objects over their resting places, so this is unlikely.

• Another reason this could have been a private burial was that this was a scandalous one, like a lady of the night. However, the elevation, sentimental atmosphere of the hill and the rock placement would seem at odds with this hypothesis.

Glenthorne National Park is on land that was owned by the First Police Commissioner of South Australia, Major Thomas O’Halloran, who sailed to Australia from London in 1838. As mentioned, he was very influential, and he owned stallions in his time, which is like a modern day squillionaire collecting Maserati sports cars.

The worker and head Archaeologist suggested this was likely the grave of a prized horse, if not Major O’Halloran’s most prized horse.

The grave will unlikely be excavated (I have since learnt on the field trip that it is common consensus in Archaeology that digging is often the last resort for investigating a site, due to its destructive nature*).

The site obviously meant something special to someone, and we now have the technology to analyse/scan what is under the earth without disturbing it with shovels, and so this is what archaeologists are going to do for further research projects.


So there you have it! Our field trip last week was at Glenthorne. The horse grave was a little diversion from the main project though. Archaeologists are actually looking for this house:

This three story mansion was called Glenthorne House, built in the 19th Century. It passed down wealthy colonialist families before it was given to the military, who billeted soldiers there.

The house was burnt down in 1932, and questions remain around why it happened: Did the army blow it up on purpose? Where did they hide the rubble?

And that’s what we were digging for – an unresolved 90-yo mystery. I felt a little bit like I was in a Scooby Doo episode when I heard the brief.

Monarto Safari Park

I have never been to Africa, but I have been to Monarto Safari Park. It is the sister zoo of Adelaide Zoo, and about an hour’s drive, southeast from the CBD.

When you go in you have to brave a long dirt road where giant birds cross your path. Never forget you are facing the species that won The Emu War.

At the visitor’s centre you will be greeted with signage, souvenirs, and bugs. Oh there is a cafe too.

A Safari shuttle leaves the entrance every half an hour on a loop around the park. The zoo is about 1500 hectares of land, and they recommend allowing yourself 4-5 hours if you want to come for a day.

View from the bus.

(A fun fact about kangaroos in Australia: they are everywhere. Footage in the ghost towns at the height of COVID lockdowns showed one bounding through the city.)

The bus passes through a range of habitats. You’ll see a lot of hoofed animals like Mongolian Wild Horses and American Bisons and antelope and deer, or as a toddler was squealing behind me, “Bambi’s dad!!!”

Beyond these habitats are some nice cats:


I think across the world, people’s attitudes towards zoos can be rather varied. Some think they shouldn’t exist. Ultimately it depends on what the function of the zoo is. Monarto Zoo is part of an international network aimed at conserving threatened species. For instance, the Mongolian Wild Horses were extinct in the wild before they were reintroduced, which would have been impossible without reservoirs from our state.

The staff seem quite attuned to ethics too – for example, they would never release a prey animal for the predators to hunt, because in the enclosure the prey would not stand a chance.

So instead, beautiful critters like this cheetah get fed pre-killed meat only. The zookeepers have to work out other ways to keep the animals mentally engaged with enrichment, such as with toys and so on.

As another example, the chimpanzees get both an indoor and outdoor playground. Here are some babies tumbling inside on the hot day.

The chimpanzee centre was founded by none other than Dame Jane Goodall herself.

On another part of the loop you will meet some more superstars.


Fun fact: apparently the white rhino got its name from the mispronunciation of an African term for “wide mouthed”. Then the black rhino got its name because it wasn’t a white rhino.

Last but not least, here are some cute little meerkats.


This one is a reminder by the side of the road as you’re driving on the dirt road back out.

This blog post comes a little late after my previous one. Uni i.e. archaeology school has finally started! The requisite reading is super interesting and I will write about that when I have time. Officially juggling full-time work and part-time study now.

What are some of your experiences with wildlife?
