Rock River, WY
Rock River wildfire risk explained
Rock River's 234 buildings earn a 77th-percentile wildfire-risk score nationally under USFS's model — well above the national norm for wildfire risk. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Rock River at the 72nd national percentile — 6 points below its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Most of Rock River's buildings (60.7%) 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.
Rock River against the rest of the country
Inside Wyoming, Rock River sits at just the 42nd percentile even though it scores 77th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, Rock River ranks 7,234 for wildfire risk (1 is highest) and 23,692 by building count (1 is largest). Within Wyoming alone, it ranks 112 of 192 places by risk. See the full county-by-county picture for Wyoming on its state page.
Rock River and the insurance market
Rock River's 77th-percentile, 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.
Lowering exposure, not just insuring around it
With ember exposure the dominant pattern in Rock River (60.7% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
