YAKIMA, Wash. — A geologist hired to study growing cracks on Rattlesnake Ridge near Yakima estimates up to 1 million cubic yards of rock and soil could move down the ridge in a landslide.

But most of the material would be trapped in a quarry and not reach Interstate 82 or the Yakima River.

The Yakima Herald-Republic reports that geologist George Machan also said this week that the landslide is projected to occur sometime between now and the end of February.

A spokeswoman for the state Department of Transportation says Interstate 82 will be closed at the first sign of excessive movement or increased frequency of rock fall.

Machan says the risk of the interstate or nearby Yakima River is low.

The ground on the ridge is moving about 2.5 inches per day.
