Overview
Trout Creek Pass is an air monitoring station in Chaffee County, Colorado, operated by the US Forest Service. It contributes to ambient air quality surveillance in the Rocky Mountain region.
Trout Creek Pass is an air monitoring station located in Chaffee County, Colorado, United States. Operated by the US Forest Service, the station is part of a network that tracks air quality in remote and forested areas. As a small-scale monitoring site, it provides data on background air conditions away from major urban and industrial sources. The station operates under the US EPA Air Quality System (AQS) framework, which sets standards for criteria pollutants such as ozone, particulate matter, and nitrogen dioxide. While specific parameters measured are not detailed, typical Forest Service stations focus on ozone and meteorological variables to assess regional air quality and visibility in protected areas. The station's last reported sample date is October 10, 2024, indicating ongoing operation. Trout Creek Pass plays a role in understanding air quality in the Colorado Rockies, an area influenced by long-range transport of pollutants and seasonal wildfires. Data from this station supports the US Forest Service's mission to protect air resources and visibility in national forests and wilderness areas. Its remote siting provides valuable baseline measurements for regional air quality models.
Environmental context
Trout Creek Pass is situated in a mountainous region of central Colorado, an area characterized by high elevation, coniferous forests, and seasonal tourism. Air quality here is influenced by both local sources (wildfires, vehicles) and regional transport from the Front Range urban corridor. Monitoring at this site helps track background ozone levels and visibility impairment, which are key concerns under the EPA's Regional Haze Rule. The station's remote location ensures measurements represent regional rather than local conditions, supporting regulatory compliance and scientific research.
Frequently asked questions
Trout Creek Pass is located in Chaffee County, Colorado, United States, at coordinates 38.91 N, -106.001 W. It is situated along the Trout Creek Pass route in the Rocky Mountains.
The station is operated by the US Forest Service, which manages air quality monitoring in national forests and wilderness areas across the United States.
While specific parameters are not publicly listed, typical US Forest Service air monitoring stations measure ozone, particulate matter (PM2.5 and PM10), and meteorological variables such as wind speed and direction. These data support the EPA's Air Quality System.
Data from Trout Creek Pass is submitted to the EPA's Air Quality System (AQS), which is used to assess compliance with National Ambient Air Quality Standards (NAAQS) and to support the Regional Haze Rule for visibility protection in Class I areas.
Remote stations like Trout Creek Pass provide baseline air quality data free from local urban influences. This helps scientists understand regional pollution transport, background ozone levels, and the impact of wildfires, which are critical for effective environmental policy and public health protection.
