The rock slide in Rockville, Utah that killed two people has many wondering how did it happen and could it happen again.
Utah Geological Survey experts said it is unclear when another rock slide could take place at the Rockville Bench Mesa in Rockville, but as the freeze-thaw season continues, residents may be at a larger risk than normal.
The bodies of two people killed when a massive boulder smashed into their home Thursday afternoon have been recovered.
The hypothetical family that a group of Highland men allegedly was trying to protect when they destroyed a rock structure was more likely to die on the drive to Goblin Valley State Park than to be crushed by a falling rock.

The rock, estimated to be about 21 x 17 x 17 feet and weighing about 450 tons, slid and fell from the upper slope of Rockville Bench, began to roll downslope, collided with a large stationary boulder at the base of the slope, and shattered into numerous smaller fragments that damaged several outbuildings, two cars, and a house. Although people were home at the time, no one was injured.
The rock fall occurred shortly after a protracted storm event on February 5-9, 2010 that produced 1.38 inches of rain at the Zion Canyon RAWS station, 4.5 miles northeast of Rockville.
The Utah Geological Survey (UGS) was notified of a large rock fall in Rockville, Utah Wednesday morning that damaged several buildings. Geologists say it could have been much worse and are worried about the possibility of second boulder breaking loose.
Around 7:30 a.m., a boulder estimated to be 35-feet by 30-feet by 30-feet broke loose and rolled down a hill toward the home that Tamara Burton was renting.
Tyler Knudsen and Bob Blackett, UGS geologists, were asked by Rockville Mayor Alan Brown to investigate what happened. According to air photos, the boulder had been there for at least four years after detaching from a ledge and sliding about 20 feet and coming to a rest on a 45-degree slope above Burton’s home.
