Spring has arrived, and with it potholes, including this selection (below) from the Highlands. The hazards form when water seeps through cracks in the asphalt, then freezes, pushing up on the road surface. During the thaw, the aggregate base has weakened enough that the weight of passing vehicles collapses the asphalt and the hole expands as it is hit. Next on the schedule: Mud.
