Environmentalists and Apache traditionalists have a new legal wrench to throw into the controversial Mount Graham telescope project the University of Arizona is building. The site designated for the $200 million project is outside the area approved by Congress in 1988, according to a lawsuit filed in U.S. District Court May 25. The university pushed for the 1988 Arizona-Idaho Conservation Act because it included an exemption from legal issues over the endangered Mount Graham red squirrel and other environmental regulations, says Mount Graham Coalition's Roger Featherstone. "The law is pretty clear about the location," says Featherstone. "If they wanted to move they should have gone back through the legal process." The 21 groups who filed the suit have long maintained that the project desecrates traditional Apache shrine sites and threatens a unique mountain ecosystem.
