There’s one more geological marvel we want to see.
But before we get there we stop at a PDS to empty the grey water out of van and top up fresh water.
While there and another van pulls up and out jumps Debby Downer wanting a chat.
Moeraki Boulders? Says him after asking where we are heading. That’s a big lot of disappointment. nothing there, just rocks on a beach…
And he proceeds to launch into a general whinge about the world, life, and modern times intermingled with a racist rant or two. I curse at how slow the grey water tank drains and opt to just pretend it’s finished so I can move on quicker…
So what are the Moeraki Boulders?
Well old racist Karen was sort of right, they are rocks on a beach.
But not just any rocks, they are concretions, Septarian Concretions to be exact. Similar to the ones we saw in the cave tour only bigger. Much bigger.
What the hell are Septarian Concretions?
I’m glad you ask.
They are nodules of rock, typically spherical, usually formed in cabanate rich mudstone. They often “grow” around something, a crab claw or dinosaur bone for example, so often contain fossils in their centre.
So basically as dumbed down as I needed it explained to me, a bit of organic matter is engulfed in mud and a rock “crystal” grows around it before the mud/sand is rockyfied itself.
Time move son and the softer mudstone or sandstone is eroded from around the harder nodule leaving behind big marbles.
And if that’s not impressive enough to make you want to check them out. Well they are on a spectacular stretch of beach.
And, well
Just look at them!
There are other, similar concretions 20km south at Shag Point (Teheheh, Shag!) that contain plesiosaur fossils but we are heading north…
And that end’s our New Zealand adventure, for this time. The following day is spent making our way back up to Christchurch, we’ve a plane to catch.
All in all we had a great trip. To recap here’s a list of links to all the awesome stuff we got to see and do.
Laurence, Chris, Tal, Della, Gabby, Ev, Matt, Adrian and meee
The bushfires that raged across much of Australia threw a spanner in the work of a family holiday to the south coast so some last minute phone calls were made to me old mate Della who generously offered us a couple of beds on the central coast, I threw the ropes in just in case
Laurence had been promoting some abseil trips to sea caves that looked quite alright and while under normal circumstances I probably wouldn’t have driven up just to visit them while I was in the area I thought why not drag Tal out of a mini adventure.
A quick message to Laurence to get some info and tips and he offered to meet us there and show us around.
Hey Dell, can you get Thursday off work?
It’d been about 20years since he’d done any abseiling but he was keen. A few other invites were sent out and before we knew it we had met up with the above mentioned folk and were setting up ropes above our first cave. The Nudie cave
We set ropes, and exit ladder and Matt even jumps in at the exit to test the water, then after a few quick tips and reminders me and Dell get on rope and drop on in
Dropping off the end of the rope we swim into the cave and wait for the others
Inside was surprisingly large and the pebbly beach gave an awesome underfoot massage
Gabby and Ev dropping in to join us
As he was finding his feet on the beach the only wave we saw all week swept up to smash Adrian face first into the pebbles. We shouldn’t have laughed… but we did
And then we swim out and make use of Laurences cave ladder to climb out of the water
Exiting without placing a ladder first would be difficult at best
Be a cool jump. Say I. Looking back up to the arch
Oh Coop jumps from that platform there, Says Laurence
I don’t take much convincing. Nor does Della
And then we make our way around to the next one, Pinney Cave. This is just a dunk in the ocean with a bit of a scramble out. By all reports the scramble out is much harder in normal conditions and out right dangerous if the swell is much over a foot. We must have got very lucky with not much swell at all as I found it much easier
But with Laurence’s warning only myself, Matt and Della decided to give it a crack, with Gabby and Ev opting for a dry landing on the exit route and the rest waiting for us up top.
Caution: You need low tide and a swell of under 2 feet to run this trip the way we did it. Also the rock is sharp as a finely honed cutty thing so rope protectors and good start technique are a must.
Adventure pushes your limits and lifts your soul or sumfink
