Last Spring I was south of Wenatchee along the Columbia River and got a good view of several very large landslides that had come off the high basalt slopes above the valley.
Large slide complex off of Badger Mountain
The terrace in the left foreground is the Pangborn Bar from an ice-age flood
The vertical relief of the slide is almost 2,000 feet
Slide and rock fall off of Jumpoff Ridge southwest of the Columbia
Another slide off of Jumpoff Ridge
The two Jumpoff Ridge slides viewed from a bit further away
The vertical relief of these slides is a bit shy of 2,000 feet
The area below Jumpoff Ridge is a huge landslide complex of sliding blocks. The slide complex is too big to take in and is the largest in Washington State. The slide complex extends all the way to the top of the high ridge.
