Lights & shadows on a creek

In the northern province of Loei, there is a national park called Phu Rua ('boat mountain'). It is known as being the coldest place in Thailand.
During daytime, it was very pleasant today with an average temperature of 18ºC. It allows country people to grow all kinds of flowers or vegetables. This is an area where they grow many dragon fruits.
I drove in the countryside to get to a waterfall this evening. Just before this creek falls into a chasm, the rocks hold the water into a small pond. The sun was getting low and I was able to catch this reflection on the water.
