Notes: Tunnel Log, known originally as Colonel Tunnel Log, was named for the large tunnel cut through its trunk during the summer of 1938. When the previously-unnamed giant redwood fell across Crescent Meadow Road on December 4, 1937, Roy Devoe, a surveyor for the Civilian Conservation Corps at Camp Wolverton, suggested cutting a tunnel through the fallen giant to clear the road rather than cutting apart and removing the tree. After Sequoia National Park superintendent Colonel John R. White approved his plan, Devoe and his crew used adzes and torches to carve the 17.0 ft (5.2 m) wide and 8.0 ft (2.4 m) tall tunnel and named the redwood Colonel Tunnel Log to honor Colonel White. Tunnel Log has been a popular tourist attraction ever since. A bypass near the tree allows larger vehicles to avoid the tunnel.

Other drive-through redwoods include Chandelier, Shrine, and Tour Thru. California is a walk-through redwood tunnel tree.
