2025 Sweet Grass County, Montana Wildfires
All 2025 Sweet Grass County Fires
A fire is listed here when it is located in Sweet Grass County. Each complex is counted once, through its parent: the parent carries the complex's acres, and its member fires are listed beneath it without being counted again. A fire that crossed a county line is listed with the acres that burned in Sweet Grass County, not its whole reported size. A fire located elsewhere that burned into Sweet Grass County is listed too, at its Sweet Grass County acres, and is not added to the Sweet Grass County fire counts. County lines come from a different boundary dataset than state lines, so Sweet Grass County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.
No fires are tracked in Sweet Grass County for the 2025 season. This table lists every fire the season statistics count for Sweet Grass County; for 2025 that list is empty. Statistics update with each data-update cycle, which normally runs about every 5 minutes.

Burn severity · Sweet Grass County 2025
Burned acres in Sweet Grass County for the 2025 season, split by how severely each cell of ground burned. Each figure counts the 30 m cells inside a fire's latest mapped perimeter, measured from satellite imagery. The Fires tab carries the reported season acreage.
Severity comes from the differenced normalized burn ratio (dNBR), the same index the federal burn severity programs publish, classified with the standard thresholds.
This is an initial assessment. Trees keep dying for months after a burn, so severity in forest reads conservative until the official assessments arrive after the season.
