The Colorado runs slow and dark past Rifle in January, steaming a little in the cold, ice lacing the gravel bars at the bends. River Valley Roll-Offs works the winter above that waterline — plowing driveways and parking areas, clearing walks, and breaking up the ice that builds where runoff crosses pavement. Down on the valley floor a storm can be all business: wind, wet snow, then a hard freeze by supper. What they hand back is a surface a truck can turn on and a person can walk across without picking their steps. Simple, and needed again the next time.
