Stowe's Vermont Fall Foliage air quality benefits from the Green Mountain elevated position at 300 to 900 metres, with consistent Atlantic and Green Mountain westerly winds providing reliable ventilation through the extraordinary autumn colour landscape. Vehicle traffic on VT-100 contributes seasonal tourist sources, while the extraordinary maple and birch forest provides exceptional natural filtration and Vermont's clean New England mountain air generally maintains excellent to good conditions throughout most of the fall foliage season.
