Purple and Red Lakes

1. Wonderful shot of a large salt lake, Uyuni, Bolivia. The red colour is caused by astronomical numbers of microscopic, unicellular organisms living in the water and salt crust.

2. A deep red lake at Sanetsch Pass, Switzerland.

3. Red Lake at Uyuni salt plains, Bolivia.

4. Another red lake near Albertville in the French Alps.

5. Red salt lake, Tunisia. How the bacteria survive in the intense desert heat is truly amazing.
