Summary

The Secretary may acquire land, water, and related rights inside Chaco Culture National Historical Park and the nearby archaeological protection areas by donation, purchase with donated or federal money, or by trading other property. Land owned by the State of New Mexico or its local governments can only be gained by donation or trade. Land held in trust for a tribe or tribal member can only be taken with that owner’s consent. Tribal governments may transfer their trust interests in those lands to the Secretary by trade, purchase, or donation under terms the tribe sets and the Secretary finds acceptable. The Secretary must try to trade for private lands first and should combine trades with cooperative agreements to protect remaining privately owned archaeological sites. For trades, the Secretary must offer a pool of federal lands at least three times the acreage of the private land sought, using parcels of similar type and, when possible, in blocks at least one section but never smaller than one-quarter section. Most federal lands can be used for this pool except National Park, National Forest, or National Wildlife Refuge units nominated by the private owner. Trades should be of equal value, with cash allowed to make values equal, though unequal-value trades are allowed if the parties agree and the Secretary finds it in the public interest. Lands removed from Chaco Canyon National Monument under this law may be traded for nonfederal land and will be managed under the Federal Land Policy and Management Act of 1976; transferring them to the Bureau of Land Management is not treated as a withdrawal under that Act.
