Local Environmental Conditions
Chaco Culture National Historical Park is a high desert canyon with scattered juniper and desert grasses. Pollen levels are modest but juniper season in late winter can catch visitors off guard. Windswept canyon terrain carries what little pollen exists widely.
As a landmark within Chaco Canyon, Chaco Culture National Historical Park follows the same seasonal pollen curve, opening with palo verde and mesquite from January with mulberry taking the lead through February. Grass pollen rises through March and April, and monsoon moisture from July through September brings a brief second wave of grass and weed pollen. Little spring rainfall means few natural breaks in pollen release once the season starts.

When is pollen season in Chaco Canyon?
How often is the Chaco Canyon pollen forecast updated?

Does pollen in Chaco Canyon come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Chaco Canyon based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Chaco Canyon, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
