Pond At Site Of Massive Grand Mesa Landslide Could Spill Over Soon

COLLBRAN, Colo. (CBS4) - Residents in Mesa County are preparing for a possible evacuation due to flooding concerns.

The new threat comes because of problems that have occurred after a landslide on Grand Mesa that killed three people one year ago.

The 3-mile long slide happened east of Grand Junction and the town of Collbran. The slide zone is so massive it can be seen on current Google maps.

A pond has formed at the top of the mesa. Experts say it could spill over at any moment due to the weekend rain.

The three men who were killed were checking on problems with an irrigation ditch caused by an initial slide on May 25, 2014 when a large chunk of a ridge broke off, sending soggy earth spilling like wet cement for 3 miles. The slide was about three-quarters of a mile across and several hundred feet deep at the center.
