TUCSON, Ariz. – A 69-year-old Bowie, Ariz., resident has been sentenced to probation for allegedly removing Native American artifacts from Nine Mile Archaeological Site Utah in 2012, according to the justice department.

The man was also ordered to pay $8,000 to the Bureau of Land Management, which manages the site. He is also barred from entering locations operated by the Bureau, the National Park Service and U.S. Fish and Wildlife Service and has to return any artifacts.

According to the U.S. Department of Justice:

Archaeologists date the site to the late Mogollon to early Salado period, which would make it between a thousand and eight hundred years old. During his visits, (he) excavated and removed numerous artifacts, including pottery, arrowheads, and grinding stones known as manos and metates.

Nine Mile Canyon, which is actually 40 miles long, has the one of the highest densities of pre-historic rock art in the world.

The man removed the items in April and May 2012 and once in August 2014 using shovels, trowels and screwdrivers. Court records place the losses at $4,422 for archaeological value and $4,285 for damage to the site.
