Incident Situation Report
Near Wisdom, MT: Burning for 55 days near Wisdom, Montana, the active Sand Creek Fire has maintained an average daily growth of approximately 646 acres per day, consuming 35,520 acres (14,374 ha) of beetle-kill lodgepole pine timber. Containment is now firmly established at 83%.
Northern Rockies interagency incident management teams have fortified containment lines along Forest Service roads and timber ridges. Favorable cooler nighttime temperatures and high humidity recoveries have significantly dampened fire behavior across the Big Hole basin.
Big Hole Valley Weather
High elevation (over 6,000 feet) and crisp mountain air are aiding suppression efforts as autumn approaches, with minimal interior smoke remaining.
π¨ Evacuation Advisories & Safety Levels
If you are near the Sand Creek 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.
π¨ Wildfire Smoke & Atmospheric Plume Dispersion
Heavy convective columns from the Sand Creek 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.
π‘οΈ 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.
Wildlife, Endangered Species & Ecosystem Impact
The Sand Creek Fire burns in high-elevation headwaters of the Big Hole River, home to the last native riverine population of the Arctic Grayling (Thymallus arcticus) in the contiguous United States. Fire managers implemented heavy buffer zones around tributary creeks to minimize ash runoff and thermal water pollution.

Oregon 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 Β· 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: 90β220 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 Oregon
Regional wildfire behavior in Oregon 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 Oregon 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.
