FILE - In this Dec. 13, 2013, file photo, officials survey the boulders from a rock slide that crushed a home and killed two people, in Rockville, Utah. Geologists are warning of the possibility of more rock slides in Utah like one in December that killed a middle-aged couple, flattening their cliff-side home near Zion National Park. The Utah Geological Survey released its report Thursday, April 3, 2014 saying a massive sandstone slab near the one dislodged by rain and snow in December now threatens to crash and shatter onto the slope below.
