Yellowstone was created in 1872, the world's first national park. The most outstanding feature of the park today are the thousands of hot water and underground geysers. Visible along roadways and in the back country are grizzly and black bears, over 4,000 bison, mule deer, and bighorn sheep. Most park facilities are open only throughout the summer. Mammoth Hot Springs is at the north entrance to the park. Running along a section between Canyon and Tower-Roosevelt, the Grand Canyon of the Yellowstone is famed for its spectacular coloring. Old Faithful and other geysers can be seen as well.
Park roads are open to travelers in the summer season only, weather permitting. One road, 60 miles long between Gardiner and Cooke County, MT, is open year-round. Snow- mobiles are welcome to ride the interior park roads from December to March.
The park headquarters is located at Mammoth Hot Springs, five miles from the north entrance. Located in the town of Yellowstone National Park, Wyoming.
