On the coldest mornings the San Luis Valley pools its air like water in a bowl, and Alamosa wakes to numbers that make the rest of the country flinch. That is the hour All Season's Blue Yeti is already moving: headlights, a blade down, breath hanging in the beam. Plowing, driveway and lot clearing, walks scraped to the concrete and treated at the thresholds, all of it finished while the streetlights are still on. Powder up here does not pack so much as scatter, so the job is pushing it far enough out that the wind cannot hand it back. By the time the sun clears the eastern rim and the valley begins its long climb toward afternoon, the way in is open.
