The rock at left travelled nearly a mile down the slope and picked up some significant velocity before impacting a house, hitting the back wall and damaging the ceiling before dropping through the floor into the garage and damaging the garage door. In an often-overlook advantage of the current financial crisis, the house was currently in foreclosure and therefore not occupied at the time of the damage. Read on for links, more info and a map of the location so you can view the terrain. (Photo by Provo Fire Department by way of Utah Geologic Survey)
