Gettysburg's National Military Park air quality benefits from the elevated Pennsylvania Ridge and Valley terrain, with consistent Appalachian westerly winds providing reliable ventilation across the historic battlefield landscape. Vehicle traffic on the surrounding Emmitsburg Road contributes modest local sources, while the extraordinary 6,000-acre preserved battlefield's open meadows and woodlands provide natural ventilation and the park generally maintains good to moderate conditions throughout most of the year.
