BOISE, Idaho — Two 500-year-old skeletons discovered in Idaho’s high desert plains will be turned over to Native American tribes. U.S. officials in a series of notices starting Friday say the remains of the young adult and child will be given to the interrelated Shoshone-Bannock Tribes in eastern Idaho and the Shoshone-Paiute Tribes in southern Idaho and northern Nevada. The notices start a process allowing other tribes to make claims until June 28.
