"Education park ranger Jessie Snow and Allison Bate, an AmeriCorps member who works in an educational capacity at the park, saw an opportunity. They figured that if they responded on the park’s Facebook page, they could not only thank Karina publicly but also spread a message.
“This isn’t just an issue for this one girl,” Snow says. “It’s very visible that things are moved a lot in the park; there’s a lot of damage on the park, people inscribing in trees, movement of materials and rocks. … It’s a very common issue here.” . . .
"Already, you are becoming an amazing steward for the park,” the message said.
“Thank you for recognizing that what is in the park should stay in the park. If every visitor took a rock home, that would mean 11 million rocks would be gone from the park every year!"
