An Alaska Army National Guard helicopter drops approximately 700 gallons of water from a “Bambi Bucket” onto the Stetson Creek Fire near Cooper Landing, on Alaska's Kenai Peninsula, on June 17, 2015. An El Niño episode was underway, and the region was drier than average that summer as well as the preceding winter—typical of El Niño. Photo by U.S. Army National Guard Sgt.
