From the WashPost, see: The West is so dry even a rainforest is on fire. An excerpt:

That a wildfire has been able to burn so extensively and for so long in a rain forest is a testament to the severity of the drought that has wracked the American West from California to Alaska. Olympic National Park — which occupies much of the Olympic Peninsula just west of Seattle — just endured its driest spring in over 100 years and a winter snow pack that was a mere 14 percent of average, according to the Park Service. The glaciers that sit on the upper slopes of the park’s mountains and feed its many streams have been receding for decades — Bill Baccus, a park scientist, told the Seattle Times that the ice sheets have shrunk by 35 percent in the past 30 years.
