“The sixth largest tree in the world!”

The Boole Tree is a giant sequoia in Converse Basin grove in Sequoia National Forest, in 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 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 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 and the largest tree within the U.S. Forest Service.

My little 4 cylinder engine could not make it up the road to the trailhead. There is one section of soft dirt that I just couldn’t get past. We pulled over about a half mile before the parking lot so it added some distance to our hike. There is a loop trail or you can walk to the Boole tree and back. The Trail is nice, about 500 foot elevation gain on the trail. Once you get to the tree, there is quite a steep decline down to it which, of course, you need to come back up. The tree is great and unlike some of the other giant sequoias in the area, there is no fencing around it.
