Crack of Doom area in Newnes State Forest, NSW, Australia

A wonderful day out visiting:
    - Crack of Doom slots
    - Cathedral Cave
    - Diamond Cavern
in Newnes State Forest, NSW, Australia

GPS tracklog file is in this link:

A more detailed trip report will be written up one day ... watch this space  :-)
For now, enjoy the pictures.

Pictures - taken in 2019 November
A pagoda-like rock formation

1)  Me  :-)   ... Photographer: Jim
Bushwalking motto: No rock un-climbed  :-)

Cathedral Cave

2)  At Cathedral Cave

3)  Looking out of the cave from its back wall

Crack of Doom 2 slot

4)  In Crack of Doom 2 slot (Will be in Crack of Doom 1 slot later in photo #9.)
- A looong slot, seems to go on and on
- Constantly 50 cm wide.

5)  The end of the slot is a most difficult climb ... Refer to photo #6.
- White arrow: Yuri is climbing up now.

6)  To climb up, you'll need to be a spiderman, like Onni here !
- Left pic: Photographer: Yidan
- Right pic:
       • You can see how high up Onni is compared to Jennifer (white arrow).
       • This place is not for you if you are afraid of heights  :-)

7)  Yuri giving a helping hand to Kristina, else some of us will not be able to climb out.

Crack of Doom 1 slot

8)  Next, to Crack of Doom 1 slot ~~~
- Black arrow: Entry into the slot is behind the black arrow.
- Yellow arrows: We'll exit out of there.

9)  At Crack of Doom 1 slot ~~~
- Mostly 20 cm wide only !
- Need to inch forward sideways like a crab, even then it is still difficult to squeeze through. And so, it took us forever to reach the end.
- If you intend to come here, best is to skip breakfast and previous night's dinner.
- And if you are fatter than me, forget it  :-)
You really have to admire the very first person who dared to venture into this slot.
What if the end of the slot is not passable ?
Geez, I wouldn't like to squeeze myself all the way back out again.

Diamond Cavern

10)  At Diamond Cavern


11)  Dendrobium striolatum (Streaked Rock Orchid) growing on a vertical rock face.
- It is a small orchid with cylindrical leaves.
- Flowering stems has one or two yellow, cream-coloured or greenish flowers with reddish stripes.
- Often grows on cliff faces, like here.

12)  Yellow circle: Mistletoe
- I was told that Mistletoe is a parasitic plant, grows by attaching to a host tree or shrub. Its roots penetrate the bark of host branch and take water and nutrients from the host plant.
- There you are, learn something new everyday !


Unfortunately, all these wonderful places are in a state forest, not a national park. Any time, the NSW government can lease the forest to a mining or logging company and destroy them all  :-(

Secret to eternal happiness

The donkey told the tiger, "The grass is blue."

The tiger replied, "No, the grass is green."

The discussion became heated, and the two decided to submit the issue to arbitration, so they approached the lion.

As they approached the lion on his throne, the donkey started screaming: "Your Highness, isn't it true that the grass is blue?"

The lion replied: "If you believe it is true, the grass is blue."

The donkey rushed forward and continued: "The tiger disagrees with me, contradicts me and annoys me. Please punish him."

The king then declared: "The tiger will be punished with 3 days of silence."

The donkey jumped with joy and went on his way, content and repeating "The grass is blue, the grass is blue..."

The tiger asked the lion, "Your Majesty, why have you punished me, after all, the grass is green?"

The lion replied, "You've known and seen the grass is green."

The tiger asked, "So why do you punish me?"

The lion replied, "That has nothing to do with the question of whether the grass is blue or green. The punishment is because it is degrading for a brave, intelligent creature like you to waste time arguing with an ass, and on top of that, you came and bothered me with that question just to validate something you already knew was true!"

The biggest waste of time is arguing with the fool and fanatic who doesn't care about truth or reality, but only the victory of his beliefs and illusions. Never waste time on discussions that make no sense. There are people who, for all the evidence presented to them, do not have the ability to understand. Others who are blinded by ego, hatred and resentment, and the only thing that they want is to be right even if they aren't.

When IGNORANCE SCREAMS, intelligence moves on.

* * * * *   * * * * *   * * * * *

Man: What is the secret to eternal happiness?
Wise man: To not argue with fools.
Man: I disagree.
Wise man: Yes, you are right.

Tessellated Pavements - 3

I am attempting to document all the tessellated patterns on rocks I have encountered.
This one is seen on the way to Bonnum Pic in Nattai National Park, NSW, Australia.

Other tessellated rock patterns I have photographed are in this link:

Sugarloaf at Hallett Cove, SA, Australia

Sugarloaf is an interesting rock formation at Hallett Cove Conservation Park, SA, Australia ... not a man-made volcano in an amusement theme park  :-)


The easiest way to see the Sugarloaf is to park your car at the end of:
    Heron Way, Hallett Cove, SA 5158
Then take a short walk ... follow the signs.

Pictures - taken in 2019 August

1)  Approximately 280 million years ago, the ice that had once covered the area of Hallett Cove Conservation Park began to melt causing a lake to form in that area. During this time many sediments were deposited into the lake which after many years turned into the beautiful unusual shaped rocks in this and the following photographs.

2)  The main feature of these rocks is called Sugarloaf named because of its resemblance to a mass of hard refined sugar.

3)  The shape of the Sugarloaf is like a cone due to weathering and erosion over the last few thousand years. However the layers tell a much longer story.
- Around 280 million years ago, southern Australia (including Hallett Cove) was covered by an ice cap. It melted about 270 million years ago.
- The lower red layers of boulders and sediments were deposited on the bottom of an ancient glacial meltwater lake.
- When the lake drained, white sand was blown over the red sediments.
- The brown cap is clay deposited from rivers about 3 million years ago.

4)  The Sugarloaf viewed from the left side of previous pic


If you are in South Australia, you must go there to take a look !

Blair Athol Coal Mine

I had a pleasant day out exploring Blair Athol Coal Mine in Blue Mountains National Park at Mount Victoria, NSW, Australia.

It was the 4th mine (
now abandoned) owned by a Queensland based company called Blair Athol Coal & Timber company.

The mine adit is 300 meters long. Incline is a steady 15%. You can walk the first 200 meters. The last 100 meters is flooded.

At where it is flooded, the water level is steady at the same level all these years. It suggests that as water seeps into the mine, it also somehow seeps out at the same rate..

Pictures - taken in 2019 August

A more detailed trip report will be written up one day ... watch this space   :-)
For now, enjoy these pictures.

1)  Blair Athol Coal Mine entrance

2)  Inside Blair Athol Coal Mine

3)  Seems to be a Sydney Rock Warbler's nest ... Please correct me if I'm wrong.
Why built a nest inside a mine adit ?   :-)

4)  Raphiophoridae
Common names are: Cave Weta, Cave Cricket, Spider Cricket ... more about it in the next photo.

5)  Characteristics of Cave Crickets (Spider Crickets) are long legs, extremely looong antennae, and flightless.

6)  Hanging on the ceiling of the cave is a fungus with an intricate fruiting body.
If you know the species name, please let me know.

7)  The mine is flooded 200 meters in from the entrance.
- Unlike other mines I have visited, the water here is extremely clear. If you don't watch out, you won't notice the water and would just keep walking !   :-)
- The water level is also constant all these years ... indicating that as water seeps into the mine, it also somehow seeps out at the same rate.

8)  Steve strips to his underpants to check out the water  :-)
- Actually, people have dived inside this mine ... No, not us, not this time  :-)

9)  On our way out

10)  Afterwards, Steve (the guy in photo #8) leads us to a ventilation shaft for the mine ... about 300 meters east of the mine entrance.
- He discovered it not long ago.
- As the vertical shaft is almost covered up with vegetation, if you go bushbashing in this area, be careful. The shaft is deep. If you fall in, you'll be dead.
- The National Parks authorities may not even know about it !  As otherwise, they would have sealed it; or erect some signage to warn you about the shaft.


Visit the mine if you have a chance ... It is an interesting place.

And with luck, you maybe able to spot the Cave Crickets (Spider Crickets) ... photos #4 and #5.

But to me, the fungus in photo #6 is most fascinating.

Some websites suggest there are Glow-Worms in the tunnel.  We detected none   :-(
But if you saw some, please let me know.  I'll check out the mine again and report the finds here   :-)

Tessellated Pavements - 2

Organ Pipes National Park is a very small national park near Melbourne in Victoria, Australia.
And yet, it has many interesting features.
One of them is Tessellated Pavement.

(To enlarge the image, click on it.)

The centre part of previous pic:
Date: 2013 December

This place is not as impressive as other tessellated pavements. But still, it is not everyday you encounter a scene like this  :-)   And grass is now growing between the cracks.  In a few more decades, you won't notice the tessellation pattern  :-(

Photographs of other features in Organ Pipes National Park will be shown in a separate article one day ... watch this space  :-)

By the way, other tessellated rock patterns I have photographed are in this link:

Tessellated Pavements - 1

Tesselate Hill is a little secret in the Blue Mountains in NSW, Australia. Not many people know about this place, let alone visit it.

But it is well known to the savvy Blue Mountains bushwalkers for its tessellated rock patterns on a large flat platform.

Although it is relatively common to see rocks with tessellation patterns; yet it is very unusual to see them covering such a large area as in Tesselate Hill.

Photos and a detailed bushwalking trip report to this area are in this link:

Some sample picture are posted below.

By the way, there is only one "l" in "Tesselate" Hill. That is how it is spelt in the maps.

Pictures - taken in 2019 July
Tessellated Pavements at Tesselate Hill

1)  From where the car is parked, it takes 30 mins to climb to the summit of Tesselate Hill. Then another 15 mins to reach here, Tessellated Pavements.

At 734-meter hill summit

10)  At the summit of the unnamed 734-meter hill ~~~
There are many patches of tessellated rock patterns, but not a large contiguous area as in Tesselate Hill.

11)  One of the many patches of tessellated rock patterns at the summit of the unnamed 734-meter hill

12)  Here is another patch of tessellated rock patterns.

There are more patches than the ones shown above. Go there and check them out for yourself  :-)

Return to Tesselate Hill and the car

13)  Then it is retracing steps back to the car.
This photo is facing Tesselate Hill. It shows the route we took to the unnamed 734-meter hill.
- Left red arrow: Just behind the ridge is where our car is parked.
- Right red arrow: Summit of Tesselate Hill
- Yellow oval: Tessellated Pavements
- Yellow arrows: Route we took to the unnamed 734-meter hill (along top of a ridge)
- White oval: Wollangambe River
