Highway 1 - Rock Formation

It's been our thing to do some scenic road trip during the weekends. I have this picture that I took where me and hubby was driving along highway 1 going towards San Francisco. This capture my attention because of it's formation. It is like rocks put together to form like a house. I don't know if this is handmade or pure nature. It caught my attention that very time and with the long range lens I had that day, I did a little justice on it though it's apparent the noise on the picture.
