GRAND COUNTY – The Grand County Sheriff’s Department is warning drivers about falling rocks after one of their patrol cars was hit and damaged by a sizable rock this week.

Warms days mixed with high winds in Byers Canyon near Hot Sulphur Springs has been bringing rocks down onto the highway and in at least two cases onto cars.

On Monday, Grand County Sheriff Brett Schroetlin says one of his deputy's was helping one car that had just been hit by a rock when a second rock fell onto the deputy’s patrol car.

“We are encouraging our citizens not to stop in Byers Canyon or other areas where we have rock flow this time of the year so they don’t put their vehicles in the kind of situation we ran into this week,” Schroetlin said.

Luckily no one was hurt by those rocks, but police worry more rocks could fall as the temperatures keep switching from hot to cold.
