The relief map resurfaced a few years ago. http://www.sfgate.com/bayarea/article/Paradise-found-70-ton-elephant-at-S-F-Port-3172072.php
I once had the privilege of going up into the Ferry Building clock tower. There is graffiti up there from 1907; workmen repairing the tower signed their names on the walls, which memory tells me are unfinished tongue-and-groove. This was in 1991 and they were tearing down the freeway in front of the building. My companion and I were able to look out upon the scene through BB holes in the clock face. Wish I had a camera with me that day.
