Weekly Photo Challenge: Walls (Zhangjiajie)

< 2 Photos>

This week’s WPC challenge is Wall.

What I am showing here are not conventional architectural / building man made walls.DSC_0172

But natural walls – part of a cliff like wall in Zhangjiajie in China.

They are walls with unbelievable heights.DSC_0171

You can also see trees that cling to the face of the cliff too.

Just incredible!
