In March 2016, Death Valley National Park in California experienced a rare occurrence: thousands of yellow wildflowers covered the region in a "super bloom." Why was this unusual? Death Valley is the hottest and driest place in North America. The area's average yearly precipitation is just two inches, making it a challenging place for flowers to grow. However, in October 2015, the valley had received more than three inches of rain in some areas. As a result of the unusually wet season, wildflower seeds that had been lying dormant underground suddenly began to grow, producing an abundance of golden blooms.
