Kangaroo island has some large sand dunes called the “Little Sahara”.
They look much steeper from the top.
Especially headfirst.
But that didn’t stop us.
It was a pretty long hill.
And you could pick up some speed.
It was a lot of fun.
Except for the walking back up the hill part.
Next we will have to try it in the big Sahara!
On our way back south from Coral Bay we stopped at Shark Bay. The beach was made up of millions of shells.
In fact there are so many shells that they have formed a type of calcium rock that was quarried to build buildings when this area was settled by Europeans.
They have left the quarry as it was from the 1800s.
The closer you get the better you can see that it is just compressed shells that make up the rock.
Past the beach you can see into Hamelin Pool. It is much more saline than the Indian ocean as the water evaporates the salt concentrates. Inside the pool there are really cool living things.
Underneath the water are not rocks, but bacterial mats. There are only a few places in the world that still have these growing mats. As you move from the shore’s edge further out into the pool the type of mat changes as there are tidal differences.
There are mats of these bacteria dated to the earliest timepoints of life on the planet 3.4 billion years ago. These ones are only one to two thousand years old. We were there at mid-high tide so you can’t really see how these mats look compared to the flatter ones that were more reddish.
The mats are made up of many different types of bacterial that all coexist together and overtime they form large structures as sediment gathers and they have to move to be able to reach the sun.
There are many birds that we aren’t used to back home. Like bright pink parrots.
Or these very colourful guys.
The twelve apostles are a bunch of limestone rocks sticking out of the sea on the south coast of Australia.
They are not apostles. There are also not twelve of them. How many there are depends on how big a rock you decide to call an apostle, and there are fewer now than when they were named, but it seems there were never twelve of them.
It was cold, rainy, and very very windy when we got to the twelve apostles so we didn’t hang around for long.
One of the breaks along the great ocean road took us down a series of steps to get to a beach. The waves were crashing pretty hard.
This trapped all the foam close to the shore.
Sometimes it came up on shore and would stay behind. With the wind blowing it would then fly across the beach.
We almost got covered when a larger than normal wave came up the beach but we managed to run away and only get shoes mildly wet.
