Some winter afternoons a chinook slides down off the Front Range and takes six inches off Sloan's Lake Park in a single day; other weeks the cold parks itself and nothing moves at all. United Snow Removal & Landscaping, LLC works both kinds of winter on Denver's west side — plowing drives, clearing walks and lots, and treating the places where meltwater runs across a sidewalk and locks up again after dark. The trucks go out on the storm's schedule rather than the calendar's, which usually means the small hours. From those blocks the mountains stand up plain across the water once the sky finally clears. Having the street already open before that view shows up is the entire idea.
