The following is excerpted from an interpretive placard on Coastal Drive at the head of the footpath leading down to the former radar station:

After the bombing of Pearl Harbor during World War II, the possibility of enemy attack on the U.S. mainland became very real. At one point, Japanese submarines operated in offshore waters and actually shelled some shipping operations and oil installations off the coast of California and Oregon.

To guard against potential invasions, the U.S. Army built "farm" buildings....The cinderblock structures, complete with shingled roofs, and fake windows and dormers, housed an early warning radar station.

From the air, the sea, and even the road, these buildings appeared to be part of a working farm. In fact, they housed a diesel generator, electronic equipment, and two 50-caliber anti-aircraft guns....
