National Park Service officials shared this blurry screenshot of two men destroying rock formations in Lake Mead National Recreation Area/NPS

National Park Service authorities at Lake Mead National Recreation Area are seeking information that could be used to identify two men suspected of pushing over natural rock formations.

The two, captured by video by other park visitors, were supposedly recorded Sunday night pushing the formations from the top of a cliff along the Redstone Dunes Trail. The video gained widespread attention on social media channels.

Law enforcement park rangers are asking the public for help. If you were on the Redstone Dunes Trail on Sunday evening, or if you have information that could help identify the suspects, please contact investigators. Tips can be anonymous:

• Call or text the National Park Service-wide Tip Line 888-653-0009
• Online, go to www.nps.gov/SubmitATip
• Email investigators at [email protected]

The men, if arrested, could face felony charges.

The landscape that holds the Redstone Dunes Trail once was a vast desert, according to the Park Service. "The dunes responsible for these formations existed one hundred forty million years ago. Over time, geological forces turned the loose dunes into hard sandstone," the agency notes on the park's website.

National parks are some of the most special, treasured, and protected areas of the United States. To protect these natural and cultural resources for this and future generations, all visitors to national parks are expected to follow park laws and regulations and practice leave no trace principles to minimize their impact on park lands.
