(CNN) — After pocketing a rock as a souvenir from her trip to the Great Smoky Mountains, a young National Park visitor was feeling guilty. So she sent the rock back, along with an adorable letter — and the park rangers thanked her.
“Deep Creek was awesome! I especially liked Tom Branch Falls,” the letter says. “I loved it so much I wanted to have a souvenir to come home with me, so I took a rock. I’m sorry, and I want to return it.”
Along with the rock in question, Karina’s handwritten message arrived with a donation and a pencil drawing of the waterfall, according to the post.
In their reply, park rangers assured Karina that her rock had been returned to its rightful place in the falls and thanked her for being “an amazing steward for the park.”
“If every visitor took a rock home, that would mean 11 million rocks would be gone from the park every year! The park would definitely not be as beautiful as it was before,” the rangers wrote in their post. “Rocks in the Smokies also provide homes for hundreds of creatures, including salamanders!”
Karina’s letter included a drawing of Tom Branch Falls.

“Now that you know to leave nature the way you find it, we hope you will help share this message with others,” the rangers concluded their message to Karina. “It is always a good thing to give another the chance to discover!”
