Removal Starts of Fallen Boulder in Ohio Crews are expected to use jackhammers to remove a large boulder that fell from a southeast Ohio hillside, crushing a car and damaging a home and three other vehicles. The Athens Messenger reports (http://bit.ly/GDQye1) the boulder that fell late Tuesday is estimated at about 100 tons and 25 feet in diameter. Tim Pfaff checks out the damage to his house and car, where a boulder landed after it broke free Tuesday night from a nearby hillside in Athens, Ohio, early Wednesday morning, March 21, 2012. The boulder crushed two vehicles, damaged a house, knocked down utility poles and damaged an underground water line, but no one was injured.

They say the slide was likely caused over time by penetration of a rock fissure by tree roots and rains. Crews and specialists continue to assess the area's stability. Tim Pfaff, who owns the home the boulder struck, tells The Messenger the rockslide "sounded like a huge hailstorm" and brought lightning-like flashes.
