About Boole Tree

The Boole Tree (GPS NAD 83: 36.823889, -118.949167) is regarded as the 6th largest giant sequoia tree 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 that 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 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 grove in the world.
