Aerial view of the Colorado River Delta in Mexico

For centuries, the Colorado River emptied into the Gulf of California between the Baja California Peninsula and mainland of Mexico. But dams and diversions have reduced the delta to a trickle, resulting in the desert-like landscape seen in this image. However, conservation efforts on the parts of Mexico and the United States are helping to return the Colorado delta to its former condition.
