The Yakama Nation is asking Washington Gov. Jay Inslee to declare a state of emergency for the Rattlesnake Ridge landslide. It’s a steep slope outside of Yakima that is moving slowly and clings above a small community, a railroad corridor, Interstate 82 and the Yakima River.

After huge cracks appeared on Rattlesnake Ridge last year, geologists expect a landslide is coming at the mountain near Yakima. But they're having a hard time nailing down just when it will go.

The Rattlesnake Ridge landslide in Central Washington is moving at 1.6 feet per week. The area south of Yakima is on private land and next to Anderson Quarry where Columbia Asphalt operates. If it continues on its expected path, the slide threatens Interstate 82, a mobile home park, and possibly the Yakima River.
