Local Environmental Conditions
At Hill City Campground, nearby, within easy reach, hazel and willow thrive along the damp bank, both prolific early wind-pollinators. This area, in the vicinity, has well-kept lawns and ornamental trees in this park add their share of grass and ragweed pollen. Nearby weather stations report comparable trends across the broader stretch of the county.
Around Hill City Campground, the water-adjacent hazel and willow are early risers, usually the first pollen source active, peaking sometime in February or March. By late spring, grass pollen is climbing steadily toward a June high point, then yields to ragweed, the dominant late-summer and fall allergen through October. Regional pollen monitoring generally reflects this same pattern across nearby areas.

Does pollen in Hill City 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 Hill City 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 Hill City, 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.

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. |
