Identification: Although California redwoods are taller, giant sequoias have a larger volume. Giant sequoias reach 164-279' (50-85 m) vs. California redwoods, which top out at 377' (115 m). Giant sequoias also live longer, up to 3,500 years. Bark, up to 3' (91 cm) thick at the bottom of the tree, is fibrous and furrowed. Leaves are ¹/₁₆-³/₁₆" (3-6 mm) long, arranged in spiral whorls. Cones are 1½-2½" (4-7 cm) long. (Photo 1 is a baby tree planted in 1981, not a trick of perspective.
