A detail of L102-90, northeast view from Apr. 11, 1968 shows the eastern end of Chabot Canyon and adjacent Lake Temescal. There is still no sign of construction of the freeway in this section, again revealing it as the last section to be altered between Rockridge and he Caldecott Tunnel. Appreciation to David Gowen for his helpful comments.
