A 12-acre site located just south of Bolinas Military Reservation
on the cliff above the ocean. Construction was ultimately deferred
on the model SCR-296 fire control radar that they planned to erect
at Bolinas Point. If completed, the installation would have included
a 100-foot antenna tower, a 20-foot square transmitter building
and a 8 x 18-foot power building.
This was also the location of Harbor Defense Seachlight No. 9.
