FLAGSTAFF, Ariz. » The Hualapai (WAHL'-uh-peye) Tribe has renewed a ban on uranium mining on its land near the Grand Canyon, joining other American Indian tribes in opposing what they see as a threat to their environment and their culture.

The tribal bans add to a temporary mining ban on nearly 1 million federally owned acres around the Grand Canyon. The combined actions mean uranium-bearing lands in northern Arizona open to companies hungry to open mines are growing scarce.

Much of the uranium in Arizona is in the northwest corner of the state. The high-grade ore used in nuclear energy and for medicine is especially attractive at a time when prices for uranium have risen.

But members of northern Arizona tribes say it's not worth putting their health, water and land at risk.
