The rock walls of Yosemite, Zion and Monument Valley provide beautiful abstract images when photographed without the surrounding location. Look closely and you will find some rock climbers to give scale to the cliffs.
A truly beautiful place, a vast canyon narrowing as you go further up into the depths and walking the Narrows can only be done by wading up to your waist in the stream. Green at the bottom, soaring red and orange rock walls and the clear blue sky above. Watch out for the tarantulas!
