Sunset Point Rest Area is located on the western edge of Black Mesa and is utilized by several thousand travelers on I-17 daily. The Sunset Point vista provides spectacular views of a complex of landslide masses along the western escarpment of Black Mesa. The Sunset Point Rest Area landslide complex is about 4.5 miles (7.3 km) long with a perimeter of ~11 miles (17.7 km) encompassing 3.2 square miles (8.3 square km). This is almost certainly the largest landslide complex encountered along I-17. (Photo by B. Gootee; annotation by J. Cook.)
