If you've been feeling like you want to knock over giant piles of rocks, then Yosemite National Park might be your playground.
The park posted a video on Facebook earlier this month instructing visitors to stop building large rock towers, called cairns, and dismantle any they find. In the video, a wilderness restoration ranger gently shoves over a cairn, which appears to be several feet high.
"This dramatically oversized cairn is a mark of human impact and is distracting in a wilderness setting," the post read. "Building rock cairns also disturbs small insects, reptiles, and microorganisms that call the underside home!"
