BOURTHOUD PASS, Colo. (CBS4) – Rescue crews from Grand County rushed to Berthoud Pass Saturday morning after an avalanche.

The slide was 500 to 700 feet long and up to 200 feet across.

Grand County Search And Rescue said conditions can be dangerous because of all the snow that fell last week.

That danger is expected to continue through the weekend.

The slide did not impact Highway 40.
