Eagle, Colo. (AP) Highway officials say Western Colorado may get more mudslides this spring and summer as the heavy mountain snow melts.
Colorado Department of Transportation Rockfall Specialist Ty ortiz says melting snow erodes the gravel and clay that hold boulders in place.
That may lead to more mudslides like one that struck Sunday on U.S. 6 west of Vail, where a 20-foot-wide jumble of mud, trees and rocks poured onto the highway.
It closed a one-mile stretch of the highway.
CDOT geotechnical engineer Mark Vessely says steep slopes and soil types determine whether mudslides occur, but there's no way of predicting them.
