Fire-scarred Giants Refuse to Die Only repeated major fires can pierce nonresinous se quoia bark, which is some times two feet thick. Charred, the tree grows a new hide. This wound's curling lips show gigantea's healing power. Except in rare cases, only falls kill the sequoias (page 170). But thin-skinned young sequoias fall easy prey to flames. Flame-hollowed Room Tree will keep its cavity but heal its "window," from which these boys are seen, and its "door" (upper left), which admitted them. Fire wounds mark most sequoias; some scars ap pear even more ghastly than this 65-foot cleft.
