We left Perth to go north. Our first stop was the Nambung National Park to see the Pinnacles. They were so cool. The Pinnacles were natural limestone structures, formed approximately 25,000 to 30,000 years ago after the sea receded and left deposits of sea shells. Over time, coastal winds removed the surrounding sand, leaving the pillars exposed to the elements. You could drive through them down sandy tracks and get out and wander among them. Very awesome, especially for a national park, usually known where we're from for not allowing access. We were there taking photos and driving around for ages.
We stopped at the car park at the beach opposite and made lunch.
Next stop was another lake with ancient structures, this time stromatolites. Lake Thetis was small, shallow and triangular and just more than two metres deep. It is double the salinity of the sea as it became isolated about 4,800 years ago. These stromatolites are estimated to have been growing for about 3,500 years.
We then drove to a campsite on the beach with toilets. It was free for now but the council wanted to introduce a fee of $20 per night which is a shame. I watched a bit of the Eels NRL game on my phone with the limited reception we had. It was quite windy being on the beach but it died down later in the evening.
