Staff from the Denver Zoo Conservation Alliance had just returned from a field project near Minturn, Colorado, when they noticed something unusual. As they stepped out of the vehicle, a marmot—an alpine-dwelling ground squirrel—poked its head out from the truck’s wheel well. The animal had unknowingly endured a 160 km (100 mi) ride along winding mountain roads to the zoo’s parking lot in Denver.
Despite the long trip and the tight, exposed space, the marmot was unharmed. Zookeepers quickly moved in to assess its condition, and after determining it wasn’t injured or stressed, they gave it a temporary home at the zoo while planning a safe return.
How the Marmot Ended Up in the Truck

Marmots are known to crawl into warm, shaded areas of vehicles, especially during cold mountain mornings. The marmot was likely seeking shelter when the conservation staff unknowingly packed up and drove off.
These animals, common in the Rocky Mountains, are members of the squirrel family and typically weigh 3–6 kg (6–13 lb). They hibernate for months at a time, so when they’re active, they’re on the lookout for cozy spots—and the underside of a truck fits the bill a little too well.
What makes this story even more surprising is that the marmot didn’t flee or panic during the long drive. Zookeepers described the rodent as “alert but calm,” a sign that it hadn’t been traumatized by the journey.
Why This Adorable Incident Shouldn’t Be Taken Lightly
Though this case had a happy ending, it’s a strong reminder for outdoor enthusiasts and locals in mountain regions:
- Wildlife often use parked vehicles as shelter, especially in rural or forested areas.
- Small mammals like marmots, chipmunks, and even snakes have been found hiding in car engines, wheel wells, or undercarriages.
- These situations can be dangerous for both the animal and the driver—unexpected movement or overheating can lead to injury or death.
Drivers are encouraged to do a quick walkaround of their vehicle—especially in natural areas—before starting the engine.
Simple Steps to Prevent Wildlife Hitchhikers
Here’s how to help prevent this kind of accidental ride-along:
- Tap the hood or knock on your vehicle before starting it, especially if it’s been parked overnight.
- Inspect wheel wells, undercarriages, and engine bays if you’re in wildlife-heavy areas.
- Avoid parking directly next to brush or tall grass, which offers cover for animals.
- Never feed wildlife, as it conditions them to seek out human spaces—including vehicles.
- Use motion-sensitive lights or sound deterrents if you park long-term near wilderness areas.
Back Home and Back to Nature

After a short stay at the zoo, the marmot was transported back to Minturn—its original habitat—and safely released. Staff said the animal “bounded off into the rocks like nothing had happened,” showing just how tough and adaptable these mountain creatures can be.
While this marmot got lucky, the story serves as a real-life reminder that wildlife and humans often cross paths in unexpected ways. With a little awareness, we can make sure those encounters end safely for everyone.
