When it fell on May 1, 1977, it was nearly a hundred feet tall (30 m) and at from the ground, in circumference. The largest branch measured from trunk to tip and the circumference of outside branches was nearly . Its age had been estimated at a thousand years, but on its demise it was found to be two trees, of 325 years each which had long ago grown into one.
Disposition For three years after falling, the tree lay on the ground whist city leaders struggled to determine its fate. In the spring of 1980 the City of Chico commissioned Cal Oak Lumber Company to remove and reclaim sound portions of the tree at Cal Oak's
Oroville hardwood plant; they were allowed to retain some of the wood as compensation. After milling the oak, Cal Oak arranged for the lumber to be dried at the
University of California's Forest Products Laboratory. Cal Oak set up a program using local artisans as well as the work training centers for the handicapped to produce a limited number of artistically designed items from its share of the tree. Many of these were given to various institutions, which included the
Royal Botanical Gardens (in honor of its namesake), the
Butte County Historical Society,
Bidwell Mansion, Sacramento Valley Museum,
Butte College,
California State University, Chico, and the University of California at Berkeley. The
Royal Botanical Gardens also received acorns from the original tree in 1981 and planted them in their gardens. Chico Fire Chief Elmer Brouillard made gavels and plaques from the wood for the Chico City Council.
Characteristics Personnel at both Cal Oak and University of California Berkeley Forestry Lab became intrigued with the lumber. The wood turned out to be as remarkable as was the tree. In order to support its immense crown, the tree grew an abnormal portion of support wood on the upper side of its limbs and stems. This type wood is known as "tension wood" and helped provide the tree with an unbelievable high density: .88
specific gravity, roughly 50% heavier than surrounding oaks. This together with other special characteristics, provided the wood with its unique grain and character, and the tree with its longevity. == In popular culture ==
