After 3 straight days of snow, Colroado's Rocky Mountains were knee-deep or higher basically everywhere you went. Thus, a day on the Moffat ensued.
Early in the morning, the Energy Mine to Valmont coal load drops down the hill with 2 SD70ACes on the front. This is one of the first trains through since the snow stopped, and no trains have gone through the siding yet. That would change about two hours later.
