Mendocino County holds a grim record — the 2018 Mendocino Complex Fire became the largest fire in California history at the time, burning over 459,000 acres. The county's dense forests, rugged terrain, and limited road network make both wildfire spread and evacuation extremely challenging. The Russian River adds winter flooding risk.
