Finally I think I've got a picture which is good enough for your contest. I've posted it already in one of my own posts. It's the picture from the waterfall Peričnik in Slovenia. This is a waterfall with a halfway basin and you can climb to the upper part of the fall. This part is a 20m drop approx, I think 🤔, the second part is around 50m. Let's enjoy for the last days till the winter kicks in those beautiful colors autumn gives to us.
