pink desert Libya---On the surface of the sand free corridors among the great dunes of the southern part of the Great Sand Sea lie one of the most enigmatic mysteries of the Libyan Desert - chunks of green through yellow to white Libyan Desert Glass (LDG), a mineral made up of almost 100% pure silica in an amorphous, glassy state.

From the Earth upwards is about 10 miles to the stratosphere, and short wave blue light tends to scatter giving our sky its bluish tint during the day. In the late afternoon, it is about 20 miles to the horizon plus the same 10 miles to the stratosphere. Only the long wave red light can penetrate this larger distance, so sunsets are oranges and reds, such as here giving these snowy branches an ironic "fiery" cast.
