This was taken last month, late, on a very dull overcast afternoon at the Lauriston Reservoir in Kyneton. This is the wall of the spillway, at the top there are sluice gates that open and so that in the residual run off, several different types of algae (or maybe a different age?) have grown producing these rainbow stripes.

Wonderful photo!
Thank you!
Very interesting. Nature is very artistic.
It was really interesting, I couldn’t quite believe it when I first saw it from a distance.
Great natural abstract – wonderful Earth tones too!
The colours were amazing. Difficult to get a good angle as it is a huge drop and so is heavily fenced.
Extra good job then!
Well spotted, Lisa. It looks very much like a wave-rock-type geological formation.
It does! I was lucky with the light as have been back since on a brighter day and it didn’t look nearly as impressive.
amazingly captured, not only for the colours but the time to find such a treasure
now presented for all to get visually lost in and enjoy time being capture in a shot
thank you
Glad you liked it Matty 🙂
That’s amazing, well spotted. Beautiful abstract image Lisa.
Thanks Beth
A truly beautiful abstract, Lisa, certainly lifted by the way in which you’ve made the converging stripes exit bottom right from the frame. And I love the colours themselves, too. The two, more or less white stripes, towards the right of the frame, are also important here. Wonderful image! Adrian
Cheers Adrian, I’m glad you liked it
Fantastic and colorful phenomenon – and photo!
A lucky find!
Lovely! The colours are wonderful but you’ve done a great job with the composition too.
Thank you very much!
