A few weeks back, I was exploring a rock formation near the Little Colorado River. I found a number of petroglyphs. It occurred to me that almost all the petroglyphs and ruins I've encountered in the Southwest were near rivers or streams. The ancient desert people had compelling practical reasons for living near water. I suspect, though, that they also enjoyed simply looking at it.
I love to include water in my photographs. Judging by what I see on photography forums, I'm not alone. Water can significantly improve a photographic composition. It's worth considering why.
