Is Yellowstone National Park In Danger Of Being 'Loved To Death'?
Almost like clockwork, every 60 to 110 minutes, Old Faithful shoots out a jet of steam and hot water up to 184 feet high. In summer the nearby parking lot fills and empties at about the same pace. Yellowstone Superintendent Dan Wenk says, "One of the great fears of every superintendent of Yellowstone is that Old Faithful will stop erupting when they're superintendent." (National Geographic)
