NO. 962 SITE OF BLOSSOM ROCK NAVIGATION TREES - Until at least 1851, redwood trees on this site were used as landmarks to avoid striking the treacherous submerged Blossom Rock, in San Francisco Bay, west of Yerba Buena island. Although by 1855 the original stems had been logged, today's trees are sprouts from their stumps.
