Hourglass field was located just west of U.S. Route 395 (now Interstate 15), about three miles north of what is now MCAS Miramar.
[1][2] Around the time of World War II the Navy used the surrounding area as a bombing range.
In 1969 Miramar College opened on the site of Hourglass Field as a training facility for San Diego law enforcement and firefighting personnel.
As of 2012 only a small triangle of the original asphalt remains, from runway 13/31, as part of an open field adjacent to Black Mountain Road.
Its grass plaza has narrow cobblestone features that outline an "X" and a bar reminiscent the runway layout.
