  SALT LAKE CITY—Several boulders as large as a delivery van fell hundreds of feet, destroying a chalet-style house and killing a middle-aged couple in a small Utah town outside Zion National Park, the mayor said.
  McGuire said the $380,000 house was "totally flattened" Thursday evening. "It was just like an explosion" that left a huge cloud of dust.
  "They're big slabs of stone with creases and cuts, and they're not all fastened up there," McGuire said. "They have a tendency to push out at this time of the year."
  The community is "shocked," he said. "Just complete, utter shock not being able to comprehend what happened."
  The victims' names haven't been officially released. The mayor said they were a California couple who, according to public records, moved to the area in 2006.
  "It's been tough to see the people show up and crumble into tears," Wright told KSL-TV. "It's been hard for the whole canyon."
  The mayor said that rocks are "always falling" in the town about 5 miles from Zion National Park. "That's what makes Zion canyon."
  "The snow melts, gets in joints in the rocks," Knudson told KSL. "When it freezes it expands and can trigger rock falls. It is more common in the winter, fall and spring."
