Tunnel Log

The Only Giant Sequoia You Can Drive Through

Giant Sequoia in Giant Forest in Sequoia NP, Sierra Nevada near Three Rivers, CA

Cut in 1937 to allow visitors to pass through it (and to attract visitors), Tunnel Log is one of only three remaining giant sequoia tunnel trees. The tree reflects a time when cutting through living giant sequoia trees was an acceptable practice, though Tunnel Log itself was already dead when cut.

The fallen Tunnel Log of Sequoia National Park came into being after an unnamed giant sequoia fell across the Crescent Meadow Road in late 1937 as a result of "natural causes." The following summer, a tunnel was cut through the fallen log as a visitor attraction. When it fell, the tree stood 275 feet high (83.8 meters) and was 21 feet in diameter at the base (6.4 meters). The tree's age when it fell has not been determined, but probably exceeded 2,000 years.
