Giant rocks close highway in Zion National Park

A rockslide shut down Mount Carmel Highway in southern Utah's Zion National Park last night. No one was injured. "Crews will have to blast the rock and use heavy machinery to clear it. Due to the rock fall, emergency response is not available on the east side of Zion. The Scenic Drive and Zion Canyon remains open," Park spokeswoman Jin Prugsawan told the Salt Lake Tribune.
