Beware the Indian-artifacts police
A 1990 federal law restricts commercial trade in American Indian archaelogical remains and so-called sacred objects, and pressures public institutions to hand over ("repatriate") such holdings to tribes. According to its critics, the law has begun to put a serious crimp in archaelogical investigation of the North American continent. It also menaces legitimate dealers of artifacts with prison terms over vaguely defined offenses, all while providing the adherents of certain religious tenets (those claimed to be traditional native beliefs) with powerful legal muscle not available to those of us who may hold other (or no) religious beliefs. (Steven Vincent, "Grave Injustice", Reason, Jul.). For the "Kennewick Man" controversy, the most famous thus far to arise under the law, For cases with sometimes-overlapping effect arising from a federal law which restricts trade in artifacts whose components include the feathers of eagles and other protected birds,
ANTIQUES ROADSHOW appraiser Bruce Shackelford, an independent San Antonio appraiser and consultant who deals with Indian art and culture, to call it "a dangerous field to collect in." That's because laws on the books?and ethical issues brought to the fore by Native American groups?have raised important legal and moral issues about collecting Native American objects. Here we've put together a simple primer on the laws governing Native American collecting to help new and seasoned collectors alike navigate legally and ethically in this field.
Illegal Goods
Pots are highly sought Native American artifacts.
A series of laws passed in 1906, 1966, 1979, and 1992 forbid the taking of Native American artifacts from federal land, including national forests, parks and Bureau of Land Management land, unless granted a permit to do so. Over the years, states have passed their own laws that restrict the taking of Native American objects from state land, echoing the federal laws. There are also laws that deal with pre-Columbian art and taking native works out of other countries.
Ed Wade is senior vice president at the Museum of Northern Arizona, a private institution in Flagstaff that has a repository of over 2 million Native American artifacts. Ed explains that these laws were enacted to restrict "pot hunting," the illegal excavation and sale of Native American objects. Under these laws, those who dig up artifacts from federal or state lands can be fined hundreds of thousands of dollars and can also be prosecuted and sent to jail.
If someone knowingly or even unknowingly purchases these illegally excavated objects, Ed says federal or state officials might seize them without giving any financial compensation.
Grave Robbing
Pot hunters know that they are likely to find the best objects at Indian graves. "Pieces from the graves tend to be the more spectacular ones," Bruce says. "Native Americans buried their better pieces in graves, so they are often protected from use and tend to survive in a more complete state." At the Austin ANTIQUES ROADSHOW Bruce saw two Anasazi pots that were between 800 and 1,200 years old. One of the pots had what is called a "kill hole," made in a pot when it was buried in order to release the spirit from the pot. The existence of this hole in a pot indicates that it was ritually buried.
