Guelta d&#039Arche, Chad, 1998 Photograph by George Steinmetz
"Knee-deep wading is bliss for camels in Chad&#039s Arche, a canyon
whose trapped waters hold a zoological surprise. Fertilized by
beasts&#039 droppings, algae are eaten by fish that are preyed upon by
an isolated group of crocodiles."

(Text and photograph from "Journey to the Heart of the Sahara," March
1999, National Geographic magazine)    RELATED
