Sequoia National Park marmots causing trouble for hikers and drivers

Yellow-bellied marmots in California’s Sequoia National Park are causing significant disruption for hikers and motorists. These large rodents have been reported stealing equipment, including backpacks, shoes, and trekking poles, and have even been known to chase humans after seizing items.

Beyond personal gear, the marmots are causing mechanical damage to vehicles parked near trailheads. They frequently crawl into engine compartments to chew on radiator hoses and electrical wiring, often attracted by salt from sweat or various vehicle fluids. Such damage can render vehicles inoperable, leading to expensive towing costs in remote areas.

Experts suggest the animals may be seeking salt from sweat-stained gear. To mitigate these encounters, the National Park Service advises visitors to inspect their vehicles before driving and suggests using plastic tarps to cover cars, which can act as a visual deterrent to prevent the rodents from accessing the undercarriage.
