Las Vegas' Valley of Fire State Park air quality benefits from the remote Mojave Desert sandstone canyon position, with consistent Nevada high desert winds providing reliable ventilation through the extraordinary red Aztec sandstone formations. Vehicle traffic on NV-169 contributes very modest local sources, while the remote desert setting generally maintains good conditions and windblown desert sand contributes distinctive red PM10 during wind events throughout the year.
