Got CALICHE?,2107,46340-74777-537925-0,00.html The Smithsonian Institution announced Friday that it will return the brain of Ishi, California's most famous Native American, but not to the Butte County tribes who have campaigned to reunite his remains and rebury them in his homeland in Tehama County. The museum says it will instead give the brain to Native Americans descended from the Yana, the larger tribe to which Ishi's people, the Yahi, belonged. A spokesman said the museum found Yana descendants in the Shasta County towns of Redding and Burney. His Western frontier collection includes Doc Holliday's O.K. Corral, 10-gauge, double barreled shotgun, and a similar weapon owned by Wyatt Earp, also famed for his role in the 1881 shootout in Tombstone. The school is building a 10,000-square-foot outdoor education and scientific research center 75 yards from the historic house site. It is one of six house sites on the property that school officials plan to protect and preserve. On Thursday, more than a dozen seventh-graders spent the afternoon digging holes and sifting through the dirt. The three-day dig involved 80 seventh-graders. Thirteen-year-old Justin Simons said he enjoyed being part of the dig, though it was long and messy. Susan Maki-Wallace's work as a forensic anthropologist requires an inquisitive mind and a strong stomach. It's the second part she's had to work on. The Baylor anthropology professor is used to being summoned by law enforcement officers, often in the middle of the night, and rushing to a scene of a decomposed body. She and her forensics students exhume the corpse and later analyze it for clues about the victim's age, sex and cause of death - work for which they charge nothing. It's an exciting job, she says, but not necessarily glamorous with maggots crawling all over your hands and people around you vomiting. But you're working feverishly, and you have to keep going. You remember that this was someone's loved one. As she perused mammoth bones here and in Kenosha this week, Eileen Johnson helped push back the frontiers of human settlement in Wisconsin by 2,500 years. Carbon dating already has established that the bones she is examining are 13,500 years old. That would put people in Wisconsin 1,000 years before what was previously the oldest discovered human community in the Western Hemisphere -- Monte Verde in southern Chile. Johnson is curator of anthropology at the Museum of Texas Tech University and research director at Lubbock Lake National Landmark. Sixteen individuals and organizations from across the state of Washington will be recognized for their significant contributions to the identification and protection of some of the state's most important historic properties at an awards ceremony in Olympia on Tuesday, May 11. Twenty-nine Lakota Indian artifacts left the North Dakota Heritage Center in a climate-controlled truck this week, headed for a major Sitting Bull exhibit at the Hessian State Museum in Darmstadt, Germany. Ken Woody, National Park Service interpreter at Little Bighorn National Battlefield, formerly at Knife River Indian Villages National Historic Site, is doing a book on tepees. He said there are only eight bison hide tepees left. Other items sent to Germany include a calico dress, coffee grinder, kettle and an Indian police badge. The items from North Dakota will help curators put Sitting Bull in his time -- the 1870s-1880s. The Hessian State Museum has a "small but important" collection of American Indian material, which began in the late 18th century as a result of the souvenirs brought back by Hessian mercenaries in the American Revolution. Through the 19th century it was augmented largely through donations from emigrants to the United States and Canada. One of these acquisitions was a collection assembled by a Hessian soldier in the service of the Canadian Army, who sent back things picked up among the Sioux exiles under Sitting Bull living in Canada after the battle of Little Bighorn.
