Incident Situation Report
Satellite thermal sensors aboard NOAA-21 detected renewed heat signatures covering 129 acres in rugged backcountry terrain of Beaverhead County, Montana.
U.S. Forest Service crews from the Beaverhead-Deerlodge National Forest are utilizing natural granite barriers, scree fields, and targeted bucket drops to manage the fire's eastern flank. Containment is reported at 65% with no structural threats to the Big Hole Valley ranching communities.
🚨 Evacuation Advisories & Safety Levels
If you are near the Beaverhead County Fire perimeter, stay alert for municipal emergency broadcasts and follow all designated routes. For a complete guide to Ready, Set, Go! levels and vehicle survival tactics, review our guide on evacuation levels explained.
💨 Wildfire Smoke & Atmospheric Plume Dispersion
Heavy convective columns from the Beaverhead County Fire generate significant fine particulate matter ($PM_{2.5}$). Track local air quality indices and wind-driven aerosol drift in real time on our wildfire smoke map.
🛡️ Property Defense & Home Hardening
Ember storms ignite over 90% of residences destroyed in wildland-urban interface fires. Protect your dwelling by implementing proven defensible space tips, clearing roof gutters, and creating a non-combustible Zone 0 perimeter.
Big Hole River High Country
The fire is burning at 7,800 feet elevation in the Pioneer Mountains. USFS fire managers are managing the incident for resource benefits while keeping firelines well away from pristine grayling spawning tributaries.

Montana Wildfire Trends, Seasonality & Risk Metrics
Comprehensive multi-year telemetry, historical burn extent graphs, and environmental fuel analysis.
| Key Parameter | Regional Value / Characteristics | Operational Significance |
|---|---|---|
| Dominant Fuel Complex | Northern Rockies lodgepole pine, Douglas fir timber duff & mountain grass steppe | Determines crown fire transmission and rate of combustion |
| 10-Yr Mean Burn Area | 390,000 acres (157,800 ha) | Historical baseline for multi-year fire cycle variance |
| Ignition Source Ratio | 70% Human / Infrastructure · 30% Lightning | Drives prevention patrols vs. dry lightning tracking |
| Critical Fire Weather Driver | Continental dry lightning storms & mountain-valley canyon winds | Triggers Red Flag Warnings and extreme rate of spread |
| Flame Spread Velocity | Moderate to High: 90–220 chains/hr in dry brush fuels | Dictates initial attack evacuation lead times |
| WUI Exposure Rating | Tier 2 High: Residential communities in the Wildland-Urban Interface | Determines structural defense assets and evacuation tiers |
Fire Ecology & Suppression Dynamics in Montana
Regional wildfire behavior in Montana is governed by the interplay between seasonal precipitation deficits, fuel moisture transitions, and characteristic local wind patterns. As summer temperatures climb and relative humidity drops, volatile surface grasses and understory shrubs transition into continuous flammable fuel beds. Under elevated Fire Danger ratings, fire spread can accelerate rapidly across slopes and ravines, producing intense convective columns that transport burning embers into surrounding communities.
Incident commanders and wildland fire management agencies emphasize early satellite detection using NASA FIRMS thermal infrared sensors, automated alert dispatching, and rapid aerial water bombing to anchor fire flanks before large-scale containment challenges arise. Homeowners and local authorities in Montana must maintain rigorous defensible space zones around residences, clean roofs and rain gutters of combustible organic debris, and install ember-resistant mesh vents to safeguard properties from structural loss during regional wildfire emergencies.
