A European satellite took a special photo of high mountains in South America. The image shows part of the Andes in southern Bolivia, near Chile. Some lakes sit there at heights of about 4,000 meters. The photo uses false colors, so plants appear red. Scientists use images like this to watch nature from space.
One of these lakes is Laguna Colorada. The lake is shallow and much saltier than ocean water. To human eyes, its water often looks red. The area is a nature reserve, and flamingos live around its lagoons. The lake is also protected as a wetland of international importance.
