YELLOWSTONE is the oldest national park in the world and covers 8,980 km², mostly in Wyoming: ninety-six percent of the park is located in Wyoming, another three percent is in Montana, and one percent is in Idaho.

"PETRIFIED TREES are evidence of the park's volcanic history. Trees buried by volcanic ash slowly had their organic structure replaced by minerals"

"MAMMOTH HOT SPRINGS - Heat, water, limestone, and a rock fracture system through which hot water can reach the earth's surface contribute to create the Terraces. Minerva Terrace, with its wide range of bright colours and its ornate travertine formations, is one of the favourite spots"


"LIBERTY CAP - This 11 meter high hot spring cone was named like that in 1871 by the Hayden Survey party because of its resemblance to the caps worn during the French Revolution"

"BULLMOOSE - Park employees for photo opportunities..."

"ROARING MOUNTAIN is a large, acidic thermal area that contains many fumaroles. It is located on the Norris-Mammoth section of the Grand Loop Road"

"NORRIS GEYSER BASIN is the hottest and most changeable thermal area in Yellowstone. The view from Porcelain Terrace is magnificent"

"EMERALD SPRING - Usually, the hot spring's colour indicates the presence of minerals. In Emerald Spring the 8 meter deep pool is lined with yellow sulphur deposits which combine with the reflected blue light to make this magnificent emerald green"

"MADISON RIVER LUNCH BREAK - The Madison River flows along the West Entrance road into Hebgen Lake outside the park. It has it's origin in the high plateau region of Yellowstone Park, which is notoriously cold. However, running through the most thermally active region in the United States, the water temperature on most sections of the river is remarkably warm, often more than 20 degrees Celsius in summer"

"FIREHOLE RIVER is one of Yellowstone's best known rivers due to the Firehole Lake Drive. Actually, along the drive there are several geysers worth seeing, including the Great Fountain Geyser, which erupts every 8-12 hours, spraying water over 30 meters in the air"

"PAINT POT FOUNTAIN is one of the mud pots found in the Yellowstone. In early summer the mud pots are thin and watery from abundant rain and snow. By late summer they are quite thick"
