Mt. Bullion, CA's wildfire risk, in USFS's own numbers
USFS scores Mt. Bullion at the 96th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 141 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
