NEW MEXICO A team of scientists will come to New Mexico and the Rocky Mountain West in early August with giant vibrating trucks. Sensitive detectors will be placed every half mile along back roads stretching from the plains of eastern New Mexico to Cheyenne, Wyoming.

CYBERIA A new exhibition of artifacts and documents related to the Battle of the Little Bighorn opened in Garyowen, Mont. Sitting Bull's only attested signature -- on a contract with William F. "Buffalo Bill" Cody -- as well as Capt. Tom W. Custer's revolver are on display at the Custer Battlefield Museum. The museum itself was recently founded. The exhibit is located on the site where Lt. Col. George Armstrong Custer's 7th Cavalry attacked Sitting Bull's camp on the afternoon of June 25, 1876, in the first military action of the Battle of the Little Bighorn. The Central Point, Ore., girl digging on the site of Nicholas Tack's hotel is among more than 70 amateur and professional archaeologists and historians working this week to excavate portions of Altaville, a copper mining town that boomed briefly during the Civil War. 25 mining companies sprang up with seven shipping the ore around South America's Cape Horn to smelters in Swansea, Wales, which then shipped the refined metal to Union munitions factories on the East Coast. The Altaville excavators are part of Passport in Time, a U.S. Forest Service program that employs about 1,500 volunteers each year on 150-plus historic preservation projects across the country.
