This panorama of Yellowstone National Park, located in Wyoming, Montana and Idaho, is America''s first national park. A worldwide favorite attraction in the park is Old Faithful Geyser, shown erupting 106 to 184 feet in the air. Since its formal discovery in 1870, Old Faithful has been one of the more predictable geysers and erupts an average of 17 times per day, every day. The nozzle-shaped cone in the foreground is Beehive Geyser, erupting sporadically at intervals ranging from 10 hours to 5 days. The river dividing the grassy area from the moonscape terrain is Firehole River. Pictured right of center in the background is Old Faithful Inn.
