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.

the land each fire shares with the Grand Fire, and fires that shared less than an
