Grand Mesa Geology

Collbran, Landslide
Mesa County Sheriff's Office

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.
