weeks ago,I went to Guoliang China, It's a great Valley.Steep cliff stands both side of the Valley,and in most time when you climb to the top of the cliff,you can find a easy way to walk down(I mean no need of rappel) and I found this. It's cool. More picture can be found on my blog http://up12.blog.sohu.com/67227473.html http://up12.blog.sohu.com/67227473.html
