Bar Nunn, WY
Bar Nunn wildfire risk explained
Out of every US place USFS scores, Bar Nunn lands at the 84th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 1,136 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Bar Nunn's burn probability — fire likelihood with no building count factored in — sits at the 82nd percentile nationally.
Bar Nunn's building exposure, zone by zone
Most of Bar Nunn's buildings (68.7%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
Bar Nunn against the rest of the country
Bar Nunn ranks lower within Wyoming (68th percentile statewide) than its 84th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Bar Nunn ranks 4,995 for wildfire risk (1 is highest) and 11,040 by building count (1 is largest). Within Wyoming alone, it ranks 63 of 192 places by risk. See the full county-by-county picture for Wyoming on its state page.
Shopping for coverage in Bar Nunn
Bar Nunn's 84th-percentile, very high rating is the kind of score behind a broader national pattern: insurers pulling back from the highest wildfire-risk markets, non-renewing or declining new policies outright, most visibly in California. Shopping around, not assuming automatic renewal, tends to matter here.
What would actually reduce this score
Because 68.7% of Bar Nunn's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
Where Bar Nunn's figures come from
Bar Nunn's 84th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Bar Nunn's dominant indirect exposure actually means, with real examples from across the dataset.
