Caption
This landslide destroyed three homes, two water tanks, and several other structures in the Balanced Rock Hills subdivision near the entrance to Zion National Park. It also forced temporary evacuation of condominiums and businesses near the toe of the slide. State Route 9 was damaged and closed for a brief time. This landslide is one of the largest ever recorded resulting from an earthquake of 5.9 magnitude. It is also located further from the epicenter than landslides ofthis type previously recorded (28 miles). The scarp is the fresh light-brown colored face below the cliff bands, and ranges up to 80 feet in height. The slide mass encompasses an area about 3600 feet wide and 1600 feet long. It moved down slope about 40 feet and crossed the road in several places, surrounding, but miraculously not touching a restaurant.
