Boole Tree

The Boole Tree is the 6th largest Giant sequoia tree in the world, and the largest known Sequoia on Forest Service lands. The tree was named around 1895 by A.H. Sweeny, a Fresno doctor, after Franklin A. Boole, a supervisor of the logging operation that is thought to have 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 largest tree within the U.S. Forest Service. It is located in the Converse Basin grove in Sequoia National Forest, on the edge of Kings Canyon, 5 miles (8 km) from Grant Grove in Kings Canyon National Park in the Sierra Nevada in eastern California.

Converse Basin was once the worlds largest Sequoia 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 grove in the world.

To get to the trailhead, take Forest Route 13S55 for two and a half miles. The trailhead will start at the end of the road. High clearance, 4WD vehicles recommended.
