Ancient rock carvings in a remote Utah desert have been defaced with modern graffiti, triggering an investigation as authorities search for those responsible.
Officials in Grand County say unknown individuals carved words and numbers into a sandstone wall at Tusher Tunnel, damaging petroglyphs believed to be at least 1,000 years old.
The markings include “646,” the letters “ATV OO,” and the phrase “BAJA TOYS,” all etched directly into the historic surface.
The carvings sit alongside images created by ancestral Native American Puebloan and Fremont cultures, whose depictions of people and scenes have remained preserved in the area for centuries.
Investigators say the new markings cut through that history, permanently altering part of the site.
Authorities have asked the public for help identifying those involved. The Grand County Sheriff’s Office released images of the damage, highlighting the recent carvings in red while noting older graffiti already present at the location.
“This type of damage to cultural and historical resources is taken seriously and is under investigation,” the sheriff’s office stated.
Investigators believe a Baja racing group could be connected to the vandalism, pointing to the wording carved into the rock.
Baja races are high-speed off-road competitions typically held in desert terrain and involve vehicles such as trucks, motorcycles, and ATVs.
The remote location of Tusher Tunnel, about 220 miles southeast of Salt Lake City, has not prevented repeated damage.
Photos shared by officials show older inscriptions scattered across the rock face, including names, initials, and dates stretching back decades. One visible marking is dated 1934.
Authorities urged anyone with information to contact law enforcement, emphasizing the importance of protecting irreplaceable cultural landmarks.
“Your help in protecting these irreplaceable resources is appreciated,” the sheriff’s office added.
The Utah case is part of a broader pattern of vandalism targeting natural and historic sites across the country, with recent incidents leading to fines, bans, and criminal charges.

At Pictured Rocks National Lakeshore in Michigan, four individuals from Illinois were penalized after park rangers discovered them carving large letters into cliff faces and collecting rocks from the site.
Officials say the group intended to take more than 100 pounds of material home.
The U.S. Department of Justice confirmed each person received a $500 fine and a one-year ban from entering the park. One individual faced an additional $250 penalty for removing rocks.
“Pictured Rocks is one of Michigan’s iconic natural wonders. There is no other place like it, and we will not get another one,” U.S. Attorney Timothy VerHey stated.
“Anyone who does will be punished: these four people were lucky to get off with a fine and banishment because the judge could have given each of them six months in jail.”
Officials did not release the names of those involved, explaining that misdemeanor violations resolved through fines do not always appear in public records.
A spokesperson compared the process to resolving a traffic citation without a lasting record.
Damage to protected land has also been reported in Kentucky, where officials at Carter Caves State Resort Park launched an investigation after vandalism appeared twice within days.
Park staff first discovered painted markings on a rock formation on July 8, prompting a warning on social media.
“Carter Caves is not a canvas. It’s a protected natural area meant to be respected and preserved—not defaced,” officials wrote.
Crews spent hours removing the markings, but new vandalism appeared again on July 10, forcing another cleanup effort and raising concerns about repeated targeting of the site.
Under Kentucky law, defacing public property such as rocks, trees, or signs can result in third-degree criminal mischief charges, which may escalate depending on the extent of damage.
In Michigan, a separate act of destruction targeted a botanical garden, where hundreds of peonies were cut and political messages were left behind.
Authorities say about 250 plants were damaged at the University of Michigan’s Matthaei Botanical Gardens and Nichols Arboretum, with flowers removed from a large portion of the garden early in the morning.
Investigators also found roughly 100 paper signs placed throughout the area. The messages included statements such as “Plant lives don’t matter. Human lives do.”
Garden director Tony Kolenic described the damage as an attack on both the landscape and the community.
“These peonies are not just plants, they are living beings. They’ve been nurtured over generations and bring joy, community, and connection to the natural world for so many people every season,” Kolenic wrote.
No group has claimed responsibility for the incident, according to officials.
Elsewhere in Michigan, vandalism disrupted conservation efforts at a nature preserve in Kalamazoo, where heavy equipment was damaged during a nighttime incident.
Authorities say five individuals caused an estimated $250,000 in damage to construction machinery at the Bow in the Clouds Preserve.
Equipment including bulldozers, excavators, and loaders had smashed windows and graffiti left behind with messages such as “Save Trees” and “Love Mother Earth.”
The Southwest Michigan Land Conservancy said the damage halted work on trail improvements, forcing contractors to stop operations, file insurance claims, and repair or replace equipment.
“We understand the sense of outrage that comes from seeing earth-moving machinery descend on a beloved natural area and fearing for its destruction,” the organization wrote.
“Meanwhile, less real conservation can get done while we mess around with this.”
The nonprofit added that the project had been designed to protect older trees and improve access while preserving the natural environment, contradicting the message left by vandals.
Security measures are expected to increase once construction resumes, including hiring private guards to monitor the site.
“We do wish the vandals had tried a little harder to understand what’s going on by either reading the signs, going to our website, or contacting us directly,” the conservancy wrote.
