Sertain Construction LLC often finishes a Fort Benton job site as the light's already going, the low winter sun dropping behind the bluffs west of town while a crew clears the last of the day's snow off a staged lot before knocking off. A commercial site under construction doesn't get to wait out a storm the way a finished building can — concrete has to cure, framing has to stay dry, and that means the access road and yard get cleared again at the end of the day even after a morning pass already opened them. The cold drops into the river bottom fast once the sun goes down, turning that afternoon's slush into something harder underfoot by the time the crew loads equipment onto trailers for the night. Grain elevators along the tracks catch the day's last light longer than the job sites do, a fixed backdrop to a workday that runs later in winter than most people in town ever see. That's the evening half of a full day's winter work, leaving the site ready to start again at first light.
