INPR, Tomales Bay Bombing Target and Long. 122' 57'West. The coordinates listed by the NAB, 12' Naval Dist., for the Tomales Bay Bombing Target (Target No. 1) was Lat. 38" 12'North and Long. 122' 56'West. The batteries were running low on the instrument, so the coordinates were not accurate down to the seconds and the elevation could not be determined. Abbott's Lagoon is located off of Pierce Point Road. The USACE team hiked the quarter mile trail out to the lagoon from the road. No GPS reading was obtained due to low batteries. A random visual and geophysical survey of the area was performed by Mr. Huckins using a Schonstedt Model GA-52Cx fluxgate magnetometer, but no ferrous anomalies were found.

A water-borne target was constructed in Tomales Bay under Contract Noy 4165. On 16 October 1956, Tomales Point Aerial Mine Laying Range was establtshed west of Tomales Point. It covered an area approximately 28,000 feet long and varied from 7,000 to 12,000 feet in width and was located more than 100 yards from the shoreline. Abbott7s Lagoon Bombing Target was also located in Marin County in the southern portion of Abbott's Lagoon. Revocable Permit No. 40 was granted by the State Lands Commission and took effect on 4 April 1941, granting the U.S. the legal right to use the southern portion of Abbott's Lagoon. 2. At the Tomales Bay Bombing Target Navy Aircraft used two types of practice bombs at this range. The first type was a miniature bomb with a marker charge similar to a shotgun shell. The second was a water bomb consisting of a light metal shell filled with water. No explosives were used. A public notice by the United States Engineer Office, San Francisco, dated June 4, 1941 declared Tomales Bay Bombing Target a danger zone. The danger zone had a 750-yard radius and was located 2,000 yards, 129 degrees true from the southwesterly extremity of Tomales Point. At Tomales Point Aerial Mine Laying Range wooden markers three inches in diameter, 14 inches long, and weighing approximately five pounds were dropped into the Pacific Ocean. Abbott's Lagoon Bombing Target was also a practice bombing target where U.S. Army and Navy pilots would drop practice bombs at a pyramid shaped target with sides that were approximately 25 feet long.. This target was anchored in the middle of the southern portion of the lagoon. When the practice bombs struck the target they left white stains that washed away when it rained. 3.
