This year is the 100th birthday of the National Park Service. Yellowstone National Park is the nation’s oldest, with its Old Faithful geyser and grizzly bears. Lucky Severson visited it recently and talked with sightseers about the beauty, peace and – for many – the sense of the holy that they find there. He also talked with Yellowstone’s Superintendent about the park’s future.
