English: Aerial photo of Miramar College and Hourglass Field Community Park with the lost parts of the outline of Hourglass Field superimposed.

The outline and the size and positioning of the outline are based on photographs at freeman/CA/Airfields CA SanDiego N.htm#hourglass Abandoned & Little-Known Airfields: California: Northern San Diego Area. The outline was traced from freeman/CA/Hourglass CA 45.jpg this photograph, an overhead-view arial photo on the above page. The scale is based on a length of 2,400 feet for runway 18/36 (the north/south runway). Other evidence of the scale is the alignment of the western edge of runway 18/36 compared with the taxiway leading to Runway 28 at MCAS (NAS) Miramar as seen in freeman/CA/Hourglass Miramar CA 56.jpg this photograph, another aerial photo on the above page. This is compared to the position of the indent of the "hourglass" in the still-visible remains of the runway system. The apparently-still-visible eastern edge of the runway system in freeman/CA/Hourglass CA 00.jpg this photograph, the color aerial photo of Miramar College on the above page is further evidence of the scale and positioning.
