Where the Pequannock and Wanaque valleys run south out of West Milford, winter storms tend to come in wet and heavy — the kind of snow that packs down and turns to rutted ice by morning. Three Rivers Contracting takes that on with plowing, sanding and salting for driveways, walkways and lots across the township. Heavy snow is a different job than powder; it has to be pushed early and pushed again, or it sets up like stone. The satisfaction is a lot scraped down to black while the flakes are still falling on it. When a valley storm is at its worst is exactly when the work happens.
