Yes, in many cases archaeological sites are protected by law. For instance, Federal laws require that when the Federal Highway Administration provides funds to the Georgia Department of Transportation to widen Highways 61 and 113 in Cartersville, Georgia, important archaeological sites like the Leake Site must be avoided or if that is not feasible, scientifically studied. Federal law also protects archaeological sites on the public lands of National Parks, National Forests, and Corps of Engineers' lakes like nearby Lake Allatoona.
Georgia laws protect all cemeteries including Native American grave sites on public or private lands. Archaeological sites on state owned lands like State Parks, State Historic Sites, and DNR Wildlife Management Areas are protected and no artifact collecting is allowed. Bartow County, Georgia has a zoning ordinance in place that protects Native American archaeological sites within the boundaries of the Etowah River Valley Historic District.
