Rocks

 Before we came here, we were told that Afghanistan would be phenomenally wealthy if rocks were riches.  It's hard to sufficiently stress just how mountainous, and barren, and rocky and dusty the land is.  These are comparatively small rocky upcroppings near Kandahar city.  They are typical of what you see in much of Afghanistan, at least south of the Hindu Kush.  Suddenly rocky narrow ridges will rise up like the spine on a prickly-backed fish, like in the last photo.
