In Mammoth Lakes, California, a town in the Eastern Sierra known for its skiing and outdoor recreation, tourism has been booming. ADVERTISEMENTLike many towns across the Western U.S., Mammoth Lakes has seen a surge in outdoor recreation since the Covid-19 pandemic began. Campgrounds and short-term accommodations like AirBnb rentals closed in the Eastern Sierra with California’s first round of lockdowns. Mammoth Lakes’ Forest Service office is habituated to responding to these types of incidents. Historically there have been vanishingly few serious wildfires around Mammoth Lakes that began with a camper striking a match.
