Galena's Historic District air quality benefits from the elevated Jo Daviess County Illinois ridge position at 240 metres above the Galena River valley, with consistent Midwest westerly winds providing reliable ventilation. Vehicle traffic on Main Street and the surrounding historic commercial character contribute seasonal tourist sources, while the elevated ridge position and the surrounding Lead Country woodland generally maintain Galena among northwestern Illinois' more pleasant historic town environments throughout most of the year.
