Significance
Located in a remote part of Utah, Nine Mile Canyon is often called "the world's longest art gallery" as it contains more than 10,000 images carved and painted onto canyon walls by Native Americans. It also is home to numerous archeological sites including pit houses, granaries and village locations. The canyon also contains many historic sites – such as stagecoach stations, settlers' cabins, ranches, and iron telegraph poles installed by the famed 19th-century Buffalo Soldiers - that stand as reminders of the area's pioneer history.
