landslide

The Collbran landslide is far from over. 

Last week the Colorado Oil and Gas Conservation Commission met with industry members and scientists to look at the current state of the slide. 

"When this earth flow failed, a large mound of disturbed bedrock had rotated back and created a large depression.  There's a pond in there now," said Jonathan White, a senior engineering geologist for the Colorado Geological Survey.

West Salt Creek used to flow through the valley, but now that runoff just feeds this pond, held back only by loose soil and debris.

On this week's Local Motion, KVNF's Laura Palmisano takes us on a drive around Grand Mesa with geologist Andres Aslan. On the drive, Aslan talks about the geological history of the mesa and why it's landslide prone. He also discusses May's massive landslide on the edge of the Grand Mesa near Collbran that claimed the lives of three men.

May’s massive landslide on the edge of the Grand Mesa near Collbran claimed the lives of three men. 

Geologists I spoke to said landslides in western Colorado and the Rocky Mountain region are a normal occurrence because the earth is dynamic and erosion is happening all around us. 

To get a better understanding of why experts told me the nature of the flat-topped mountain is to slide, I took a drive on Grand Mesa with a geologist. 

I met Andres Aslan, a Colorado Mesa University professor and geologist, at the visitor center on the mesa.
