Harbor Defenses of Sitka, Alaska

LOCATION : Little Biorka Island (Fort Peirce)

Base End Station B1 S1 for Battery 291
Signal Station No. 3 Searchlights No. 17 and No. 18

All of the installations planned for Little Biorka Island were only partially built before construction was cancelled in late 1944. The two searchlights were to be controlled by Distant Electric Control (DEC) stations on two separate 25 foot timber towers.
I have not yet been to Little Biorka Island to view what remains.  The Report of Completed Works for the BS tower says the tower was 90 foot tower 91% completed.
