Residents living within high rock-fall-hazard zones in Rockville, Utah, face the possible consequences of a large rock fall similar to the fatal event that occurred last December. That is the principle finding of a geologic investigation into the rock fall that killed two people on December 12, 2013. That afternoon, a huge, joint-controlled rock mass, with an estimated volume of almost 1,400 cubic yards and weighing about 2,700 tons, detached from the cliff face at the top of the Rockville Bench, near Zion National Park. The rock mass fell onto the steep slope below the cliff, and shattered into numerous fragments. The rock fall debris then moved rapidly downslope before striking and destroying a house, detached garage, and a car. The largest boulder to strike the house weighed an estimated 520 tons.

There are significant geologic hazards present along State Route 9, between La Verkin and Springdale in Washington County, according to the Utah Geological Survey (UGS). Geologists recently released a comprehensive report addressing the numerous geologic hazards that threaten the growing communities of La Verkin, Virgin, Rockville, and Springdale. All of the communities are on State Route 9 which is the main transportation corridor for more than 2.5 million annual visitors to Zion National Park. “Recent damaging and fatal rock falls in Rockville, landslides in Springdale, and floods along the Virgin River demonstrate that many of the geologic processes that have shaped this area’s outstanding scenery also make this area prone to geologic hazards,’ says Tyler Knudsen, UGS geologist.
