How does a giant slice of history cross a campus?

For the sequoia segment that greeted visitors to the Arizona State Museum on the University of Arizona campus for nearly sixty years, the answer is: carefully.

The two-ton cross section of a giant sequoia tree, which spans 10 feet in diameter and is thought to be about 1,800 years old, required a team of movers and a heavy-duty crane to make its way to its new home.

"It had to be moved out in sections and reassembled," says Chris Baisan, senior research specialist at the University of Arizona Laboratory of Tree Ring Research, which received the slab as a gift in the 1930s.

The slab will now enjoy prominent display in the Bryant Bannister Tree-Ring Building, the new home of the UA Laboratory of Tree Ring Research.
