Photo of the Day

Mongolian herdsmen drive horses back into the Darhad Valley after wintering on the other side of the 10,000-foot (3,000-meter) mountains that rise in the background. People have moved their herds over these mountains for generations. But a government effort to transition Mongolia's nomadic people to more stable urban lives could soon mean the end of this twice-yearly trek.
