Yellowstone's Steamboat geyser rare eruption

[Still Waters]

Yellowstone National Park's Steamboat Geyser — the world's tallest — has erupted for the first time in more than eight years.

The nine-minute blast sent steaming hot water an estimated 200 to 300 feet in the air, park geologist Hank Heasler said Thursday.

Unlike the park's popular and famous Old Faithful geyser, which spews water like clockwork every hour-and-a-half, no one knows when Steamboat will erupt next.
