Northwest Tasmania has fascinating geology. When we first came here the stony western end of Sisters Beach reminded me a lot of Hallett Cove in South Australia, where I used to live. Hallett Cove is also a geologically interesting site because of the evidence of glaciers in the area which is now a conservation park. I first visited there as a 14-year-old high school student. When I first saw the erratics at Sisters Beach I could not help but think of our old home.
I came across an interesting article about the similarities between rock formations in Arizona’s Grand Canyon and those in Rocky Cape National Park, Tasmania. Sisters Beach is surrounded by Rocky Cape National Park.
Here is a YouTube video on the same subject.
Rocky Cape also has some interesting archeological history. I recently read a book called “Deep Time Dreaming” by Billy Griffiths which has a section on findings in the area.
So far, I have not been into Rocky Cape National Park myself. I have only been on the beach at Sisters Beach and Boat Harbour. There are walks you can access from the western end of Sisters beach and another that goes from the eastern end to Sisters Beach Road. Some of them might be a bit too rugged for me but now that the weather is improving, I might try to go a little way into the park. Naturally it’s not a good idea to hike alone, especially when you are unfit so I’m probably never going to see all the park. We will go to the other entrance of the park at Rocky Cape one day. There is a lighthouse there and parking so it could be possible to do a short walk from there. Something that Naomi and I could manage.
At least you can see some of the unusual colouring in the rocks in some of my photos. I hope to learn more and will write more about this subject in a future post.

So did Tasmania slide down and hook onto Australia? I find this stuff absolutely fascinating. Right now, I’m learning about all the new dinosaurs they’ve been finding in Wyoming and Montana (mostly Wyoming which is Tyrannosaurus Rex central). Now I have to look more of this stuff up! I got another book in the “Gird” series of Australian history. Haven’t read it yet, but it’s high on my list.

As I understand it at this time in history Australia was in the northern hemisphere and what is now the mainland was three separate parts. At some point Tasmania slid into them. It is fascinating stuff I think.
