Two Coloradans face criminal charges after allegedly trespassing at a historic cowboy camp at Canyonlands National Park in Utah and stealing artifacts. 

Durango, Colorado, residents Roxanne McKnight, 39, and Dusty Spencer, 43, allegedly "entered a fenced-off area" of the park "where they then handled and stole numerous historic artifacts preserved in the Cave Springs Cowboy Camp" on March 23, the U.S. Attorney's Office of the District of Utah wrote in a Nov. 4 press release. 

Both are charged with theft of government property worth less than $1,000, possessing or distributing cultural or archaeological resources, and walking on or entering an archaeological or cultural resource, authorities said.

They are scheduled to appear before Chief U.S. Magistrate Judge Dustin B. Pead at the United States District Court in Moab, on Nov. 8.

"This historic camp was protected by fencing and clear warnings prohibiting visitors from entering the area, which McKnight and Spencer disregarded," authorities added in the release. Court documents say the area is protected by a log fence.

The alleged thieves disregarded clear "no trespassing" signs around the site, which houses artifacts from camps of pioneer cattle ranchers between the late 1800s and 1975, the attorney's office said.

The camp also showcases ancient rock carvings made by indigenous tribes about 6,000 years ago, according to the park's website.
