Lake Retba or Lac Rose lies north of the Cap Vert peninsula of Senegal, north east of Dakar.
It is so named for its pink waters, caused by Dunaliella salina in the water. The color is particularly visible during the dry season. The lake is also known for its high salt content, which, like that of the Dead Sea, allows people to float easily.
The Wave is a sandstone rock formation located near the Arizona and Utah border on the slopes of the Coyote Buttes.
