Nine Mile Canyon
Nine Mile Canyon in eastern Utah holds one of the largest concentrations of rock art in North America and is often called the world's longest art gallery. Most of the panels were made by the Fremont people. Hunting scenes with bighorn sheep are common along with horned human-like figures, birds and shields. Natural gas drilling above Nine Mile Canyon in the 2000s sent heavy truck traffic down its dirt road. The dust and the chemical spray used to control it threatened the rock art until a 2010 agreement funded preservation work and the road was paved.
