Alite Reef Steel Floating Signal

Figure 1
Pre-war the Solomons virtually had no navigational aids, but with the arrival of the Americans and the exponential increase in  wartime shipping, the U.S. Navy installed a vast array of beacons, lights, leading marks, reef marking buoys and twenty foot signal towers like this one on Alite Reef.
