The 2017 Bald Mountain Fire, 2019 Walker Fire, and 2021 Antelope Fire (partial) affected the county. Communities near Mammoth Lakes and the June Lake Loop face fire risk from both Sierra and high desert fire environments. The county's dry summers and terrain channeling can produce rapid fire spread.
