One of the most spectacular natural sites I've ever visited is the dreaming valley of Yosemite in northern California, with its huge waterfalls and cliffs, resembling Jurassic eras. On the moment of taking this image I was watching dance of colors in twilight sky from the high altitude Glacier Point, while I could hear sound of vernal fall (bottom left). A unique night of watching the fascinating night sky from this extremely unique point on the Earth was approaching.
