Album Info:
Vishnu Shist is the oldest rock in Grand Canyon. And a geologist once told me that it is also the oldest exposed rock formation in the world. This geologic formation is over 1.7 billion years old. This extraordinary formation of Vishnu is backlit on the Clear Creek trail by the rising sun.
