Acres are the land the fire burned in each county and community, and places where it
burned less than an acre are not listed. Communities are cities, towns and the unincorporated places the
Census Bureau names, so land outside any of them is counted only in its county.

fires that burned less of the same land. Acres are
the land each fire shares with the Mcnally Fire, and fires that shared less than an
acre are not counted. Some older or smaller fires may be missing, and a fire perimeter can include unburned
patches. How to read fire history
