Rocky Mountain National Park's air quality benefits from its elevated Colorado Rocky Mountain position at 2,700 to 4,345 metres, with consistent high-altitude westerly winds providing excellent natural ventilation. The extraordinary alpine wilderness generally maintains good conditions, while nitrogen deposition from Front Range urban and agricultural sources affects sensitive ecosystems, summer wildfire smoke is an increasingly severe seasonal concern, and summer ozone from Front Range and regional sources is a documented air quality challenge throughout the year.
