A commercial lot tells you the truth about a storm: every inch that fell is still sitting there under the sodium light, waiting on somebody. Rocky Mountain Asphalt runs Steamboat Springs lots and drives after the shops along Lincoln Avenue have gone dark, pushing the night's accumulation into corners where it will not steal a parking space by morning. There is a real geometry to the work — where the piles go, where the melt will run, which approach keeps the entrance open for the first delivery truck. Clean asphalt at six in the morning, steaming faintly in the cold, is the whole signature. West along US-40 toward Milner the routine repeats, for as long as the sky keeps handing it over.
