This week’s Photo Challenge gave me a bit of a challenge – but hey, it’s in the name! – as I will be outside all week, so how to interpret the theme!?
This rock is called an aeolian sandstone. Deposited by the wind… about 200 000 000 years ago.
When you look closely you can see a number of clear, slightly darker lines. It is clearly visible in the top left, but also within the band lower in the photograph.
New layers or beds, overlying older ones, at a slight angle – called crossbedding. By knowing the original orientation of the rock it is possible to say from which direction the wind was blowing so long, long ago.
In some places, this rock has been painted on by Native American cultures. Pictographs of people and snakes – 2000 year-old art.
In other places you can see footprints of dinosaurs – ‘terrible lizards‘ – that walked the Earth long before mankind even existed.
So, I have taken you inside history…
It’s always nice to combine business with pleasure 🙂
Acknowledgement: I would like to thank Mr. Lizard for his excellent modelling efforts, the photo wouldn’t be the same without him 😉
