This comprehensive guide is the first to focus on all the giant sequoia groves in the state of California, not just those that are well-known. The author has identified sixty-seven different groups of these forest giants, and has organized them into five different geographic areas from north of the Kings River to south of the Tule River watershed. Extensive information is provided for each grove including general description and managing agency; historical facts; size, condition, and overall quality; access; and notable trees.
