PARADISE, MI - Tahquamenon Falls State Park is asking people to stop stacking rocks along the river, saying it is damaging the environment, particularly for the insects who call the river home.

The bottom of the fast-flowing Tahquamenon River is filled with lots of flat sandstone rocks. It seems many people can't resist the urge to stack them like elaborate Jenga towers, leaving their "artwork" for other tourists to admire.

But insects like stoneflies - which are snapped up by hungry fish and other animals - also love clinging to these rocks in the river. So when humans haul out the rocks and stack them on shore, they're inadvertently killing these little guys.

The state park put out a video this week on Facebook, asking people to stop stacking the rocks.

"Unfortunately ... all the habitat these little guys need to live on are being stacked up and taken away from them," the park naturalist said. "They're not going to live much longer if they don't have anywhere to stay."

"The best things to do is knock these towers back over and put the rocks back in the water." she said.

The park shared the hashtags: "knockthemdown" and "norocktowers."

In backcountry hiking areas, these rock "cairns" serve a purpose, reinforcing trail maps and marking hiking routes in some parks. But the ones we see on Michigan beaches and places like Tahquamenon are often just decorative.

Aside from being damaging to the ecosystem - as evidence by the squished stoneflies found between rocks - this rock art also really rubs some people the wrong way.

A movement gained traction a few years ago to ban these rock piles from beaches and other areas, with some people calling the stones litter or beach graffiti.

Tahquamenon Falls State Park, located both in Luce and Chippewa counties, is a big tourist destination in Michigan's Upper Peninsula. Its Upper Falls stretch more than 200 feet across and drop nearly 50 feet down with a crash of cascading water.

The Lower Falls is actually a series of smaller waterfalls. The river's signature brown color comes from the tannins from nearby cedar swamps, which flow into the river.

Earlier this year, videographer Dustin Dilworth of D3 Imagery captured an amazing meteor show amid the Milky Way sprawling overhead at the park.
