All 2025 Sublette County Fires · 4 fires

A fire is listed here when it is located in Sublette 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 Sublette County, not its whole reported size. A fire located elsewhere that burned into Sublette County is listed too, at its Sublette County acres, and is not added to the Sublette County fire counts. County lines come from a different boundary dataset than state lines, so Sublette County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.

Burn severity · Sublette County 2025

Burned acres in Sublette 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.
