Converse Basin used to be a large grove, but was logged of most of its giant sequoias between 1892 and 1918. Now only perhaps 60 large specimens survive out of thousands. This grove is the largest contiguous giant sequoia grove in the world. The 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's life due to its great size.
Before 1931, it was thought to be the largest tree in the world, but it's now known as the sixth largest tree, after 5 other giant sequoia: the General Sherman tree, the General Grant, the President tree, the Lincoln tree, and the Stagg tree.
The girth of this tree is not known.
