36 degrees 35' 03" N 121 degrees 28'23" W 250 feet in diameter.
Retired Navy Captain Mark Wood has analyzed Google Earth images of the Chualar, California, field and concludes the diameter of the December 28, 2013, pattern in the 2 to 3 foot barley is 250 feet. The difficulty in estimates by people on the ground is that the land within the large rectangular frame sinks down like a shallow bowl. From the telephone pole on the south (far right above aerial), only the southern parts of the pattern could be seen. Aerial © by 111th Aerial Photography & Video.
