Mammoth, PA
Mammoth wildfire risk explained
USFS's Wildfire Risk to Communities model puts Mammoth at the 34th national percentile for risk to structures, close to the middle of USFS's national wildfire-risk range — a score built from 383 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Mammoth's burn probability — fire likelihood with no building count factored in — sits at the 34th percentile nationally.
What "at risk" means for the buildings here
Of Mammoth's 383 counted buildings, 60.8% carry Direct exposure and only 0% carry Minimal — a lopsided split that puts defensible-space clearing ahead of vents or roofing as the intervention worth doing first.
Mammoth against the rest of the country
Mammoth scores 34th nationally and 47th within Pennsylvania — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Mammoth ranks 20,873 for wildfire risk (1 is highest) and 19,573 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,062 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
What this risk score means for insurance
Mammoth's moderate rating (34th percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
What would actually reduce this score
Mammoth's 60.8% Direct-exposure share means lot clearing around the structure typically outweighs any single material upgrade here. The home-hardening guide ranks the options for a place shaped like this.
