Sparse Snowpack Worsens California Drought Crisis

March 6, 2014---"It could be pretty grim," says California's chief of snow surveys, looking toward the summer months. During one of the worst droughts in centuries, state officials are concerned. The snowy stockpile of water in the Sierra Mountains is the state's real reservoir, supplying about a third of the water used by farms and cities when it melts each spring and early summer. National Geographic followed California’s top snow surveyor on a recent snow inspection, and he's sounding the alarm.
