The Boole Tree was named around 1895 by A.H. Sweeny, a Fresno doctor, after Franklin A. Boole, a supervisor of the logging operation who spared the tree due to its great size.
The Boole Tree was once thought to be the largest tree in the world, but it is now known to be the sixth largest, with five other giant sequoias surpassing it in size: the General Sherman, General Grant, President, Lincoln, and Stagg trees.3 Despite this, Boole is still the largest in terms of circumference, with a base measuring 113 ft (34 m).
Located among shorter Scouler willows that have grown in the area following logging, the tree stands out at a height of 268 feet. It is likely growing faster due to a lack of competition in its modified environment, and its survival may also be attributed to the reduction of fuel in the area since logging ceased in the 1900s.4
