Gibber Plains are an amazing feature of the northern Australian landscape. The rocks are called gibbers; they are coated with a mineral deposit that makes them look like they have been through a tumbler and partially polished, and form what looks like a pavement. When viewed from a low angle, they glow with pink or purple reflected light. The single tree in the far distance is a gidgee, a semi-desert species of acacia. A very lonely landscape.
