Hans, Akira, than you.
Yes, there are a few burnt highlights in the first one but it was shot in jpg only mode (the crappy "low" iso mode on X-T1 which doesn't allow for RAW, I discovered it that day!). There is no room for recovery unfortunately.
Akira, these rock piles can be found by hundreds at some accessible places on that river. My son built a few as he liked the challenge.
I think they are present in a few cultures, including the Himalayans, and are supposed to connect people to nature.
I oftent think of Antoine de Saint-Exupery when I see them: a rock pile ceases to be a rock pile when just one man contemplates it with, in him, the image of a cathedral (poor translation from French).
