All 2026 Big Horn County Fires · 4 fires
A fire is listed here when it is located in Big Horn 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 Big Horn County, not its whole reported size. A fire located elsewhere that burned into Big Horn County is listed too, at its Big Horn County acres, and is not added to the Big Horn County fire counts. County lines come from a different boundary dataset than state lines, so Big Horn County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.
