Steamboat Geyser, in Yellowstone National Park's Norris Geyser Basin in Wyoming, erupts on Wednesday, July 31, 2013. Steamboat Geyser — the world's tallest — has erupted for the first time in more than eight years. Park geologist Hank Heasler says Wednesday night's nine-minute blast sent steaming hot water an estimated 200 to 300 feet in the air.
