The Grand Loop Road Historic District encompasses the primary road system in Yellowstone National Park. The US Army Corps of Engineers originally planned much of the 140-mile system in the early days of the park, when it was under military administration. The Grand Loop Road provides access to the major features of the park, including the Upper, Midway and Lower geyser basins, Mammoth Hot Springs, Tower Fall, the Grand Canyon of the Yellowstone and Yellowstone Lake. A number of other historic districts adjoin the Grand Loop in Yellowstone, including Mammoth Hot Springs, North Entrance Road, Roosevelt Lodge, Lake Fish Hatchery and Old Faithful historic districts. Grand Loop Rd. includes unsigned portions of US 20, US 89, US 191 and US 287, all of which traverse the park. Wikipedia"
The Old Faithful Visitor Education Center features exhibits on Yellowstone's hydrothermal features (geysers, hot springs, mudpots, and fumaroles), life in these extreme environments, the volcano beneath Yellowstone, and ongoing scientific research in one of the greatest living laboratories on earth. Children of all ages will enjoy the Young Scientist exhibit room, which includes a geyser model, hands-on exhibits, and a gathering space for classes and other organized groups. Evening ranger-led programs are presented during the summer and the winter seasons. The Old Faithful Visitor Education Center was built to minimize its impact on the natural surroundings and is a LEED certified building. Located across the west parking lot are a combination ranger station, backcountry office, and clinic. This facility also houses the office of the district naturalist and the district library. NPS
