Las Vegas's Red Rock Canyon air quality benefits from its exceptional Mojave Desert National Conservation Area position in the Spring Mountains at up to 2,000 metres, with consistent westerly desert and mountain winds providing outstanding natural ventilation above the Las Vegas valley floor. The park's remote natural setting and the elevated sandstone escarpment position generally maintain excellent conditions well above the Las Vegas metropolitan valley inversion layer throughout most of the year.
