Children walk among wildflowers in Death Valley National Park, in Death Valley, California, March 3, 2016. Unusally heavy rainfall in October trigged a &quot;super bloom,&quot; carpeting Death Valley National Park, the hottest and driest place in North America, in gold, purple, white and pink. The bloom is the parks largest in a decade.&amp;nbsp; Photo: ROBYN BECK/AFP/Getty Images
