HORSESHOE BEND, COLORADO
The Colorado River flows 1,470 miles (2.366 kilometers) from the Rocky Mountains to the Gulf of California's Sea of Cortez—or did when its waters were more plentiful. Reduced rainfall and the growing water demands of some 30 million thirsty Westerners have sucked some of the life from the Colorado, and these days its delta is often dry.
Some scientists warn that changing climatic patterns and unchecked human use could dry up the river’s reservoirs within a couple decades.

SUNSET AT LOWER LEWIS RIVER FALL, WA
The sun sets over Lower Lewis River Falls in Washington State’s Gifford Pinchot National Forest. The falls mark a wild and scenic stretch of the river, but other sections of the Lewis, which drains the state’s mighty Cascade Range, boast large dam and reservoir systems.
Hydroelectric plants produce power, but they’ve changed the river’s natural character—to the special detriment of migratory fish like salmon. Utilities have agreed to begin trucking fish around the dams along the Lewis River, moving them from below these looming barriers to prime habitat upstream, above the dams.

HOT SPRINGS, EAST AFRICA Sulfur and algae turn hot springs into pools of living color. The water is condensation from hot gases rising from magma chambers. As the water evaporates, salts and minerals form a vivid crust. Photograph by George Steinmetz, National Geographic |
