Back to School in America's National Parks, New NPS Website Helps Teachers Make Learning Relevant and Fun
WASHINGTON (NPS Press Release) – Fifty-five million school kids are about to learn that America’s 401 national parks aren’t just for vacations.
Yellowstone National Park's Steamboat Geyser — the world's tallest — has erupted for the first time in more than eight years. On July 31, 2013, the nine-minute blast sent steaming hot water an estimated 200 to 300 feet in the air. 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. In the past, it's gone as long as 50 years without a major event. In 1964, it erupted a record 29 times. The last blast came in 2005.
