Weekly Photo Challenge: Foreign
Walking on the beach today I spotted a foreigner … no not a holiday maker but a totally out of place rock. The rock at the top of the picture is the natural rock – it looks like it is folds or pillows of pyroclastic flow (lava rock) in a soft grey or sometimes green-grey colour.
The rock at the bottom is a dark grey granite type rock and the only one I have seen on this three mile stretch of beach.
That got me thinking then about things that we leave as foreign on the beaches – bricks are a good example but interestingly although foreign to the beach in this shape and form they actually will break down eventually into more beach!
I am going to include more about rocks and pebbles on this beach in my next post later this evening if you are interested in geological stuff.
