Waterfalls in JiuZhaGou

Here are two more pictures taken in Jiuzhagou, China.
I must admit that they illustrate more of serene scenery than mere boundaries.
The first one appears to me to be an infinity pool with water flowing towards the temple.
Somewhere between the lake and the temple must be a boundary – a boundary which is hidden by the fact that there is a fall between them.
The picture was taken at a high altitude in Huanglong, a few thousand metres above sea level.
In the second picture, there is a definite boundary – a timber fence which separates the visitors from the hills and lake below.
Mentally, the boundaries are just invisible, as you have become immersed in Nature!
This week’s DP photo challenge is Boundary.
The trees on this picture and the fence mark the boundary to the lake.
However, the beauty does not just stop at the boundary, it continues on to the blue crystal clear lake and beyond.
Beauty cannot be contained within boundaries; it penetrates through until it reaches the heart and mind of those who see it.
The Photo Challenge of the Daily Post this week is Refraction.
This is a photo which I have not shown to anyone.
Not many people can understand what is shown in the photo without any explanation.
This is what you see when you view down the clear calcium rich waters of the lakes in Jiuzhaigou, China.
This is also a perfect example of Refraction ( this is not to be confused with reflection which some people have submitted for this photo challenge).
When I studied physics in high school, I understand that when a wave travels through medium of different refraction index, its speed of travel changes according to the medium, this is detectable when say, light (as a wave), travels in water and air etc.
The picture shows not only fishes in the clear water but also tree trunks which have fallen into the water. The tree trunks look bent from their original straight alignment when immersed in the lake water – a good example of refraction.
If you look directly over the lake water, the bottom is the lake appear shallower, again, a result of refraction.
The Daily Post asks us to show a picture to show our understanding of refraction; this is perhaps the best example that I can give!
