A tourist dropped a packet of Cheetos in Carlsbad Caverns National Park, causing a ripple effect that could have disrupted the ecosystem. Read about the unexpected consequences of this seemingly small act.
A seemingly innocent act by a tourist in New Mexico’s Carlsbad Caverns National Park has led to a surprising warning about the potential consequences of littering in natural spaces.
On September 6, 2024, the Carlsbad Caverns National Park’s Facebook page shared an alarming message after a hiker dropped a packet of Cheetos in the park’s famous “Big Room.” The park, located in the Guadalupe Mountains of southeastern New Mexico, is home to more than 119 caves and is known for its breathtaking limestone formations and unique desert wildlife, including bats, cougars, and cave swallows.

This National Park is the largest cave chamber in North America by volume, with the “Big Room” stretching almost 4,000 feet long, 62 feet wide, and 255 feet high. With such an expansive and delicate ecosystem, even the smallest disruptions can have significant ripple effects.
Why Cheetos in Carlsbad Caverns Matter
In the Facebook post, park officials explained that while the Cheetos packet might have seemed trivial to the person who dropped it, it had a huge impact on the cave’s delicate ecosystem. The post stated, “At Carlsbad Caverns, we love to host thousands of visitors each day. But even small impacts can lead to major consequences.”

The chip packet, left off-trail in the Big Room, created the perfect environment for microbes and fungi to thrive, thanks to the processed corn in the Cheetos, which became softened by the cave’s humid air. Insects, including cave crickets, mites, and spiders, began to feed off the remnants, forming a temporary food web. This resulted in molds spreading higher up the cave surfaces, which eventually died and began to stink.
This seemingly harmless snack turned into a larger problem, illustrating how even small actions can have a “world-changing” effect on the environment, particularly in sensitive ecosystems like Carlsbad Caverns.
A Cautionary Tale for Future Visitors
Park officials emphasized that while the dropped snack may seem insignificant from a human perspective, its effects on the cave’s life cycle were much more profound. “Great or small, we all leave an impact wherever we go. Let us all leave the world a better place than we found it,” the post concluded.

Although the person who dropped the Cheetos was never publicly identified, the park did confirm that its rangers successfully removed the discarded packet and cleaned up the mess to protect the cave’s fragile environment.
So, next time you’re exploring a cave, remember to keep a tight hold of your snacks. Your simple act of littering could set off a chain reaction that disrupts an entire ecosystem.
