If I'm not mistaken I believe it is a clear zone for munitions and solid rocket fuel which this base was used to dispose of.

They're mentioned on commercial airport sites -- also called "compass calibration pads"
A final installation step is to perform a heading calibration. Heading calibration compensates for any magnetic field created by the aircraft. It consists of putting the unit in calibration mode, and rotating the vehicle in a circle. Most airports have a compass rose, which is the best place to perform the calibration. Unlike some other heading systems, you do not need to position or point the plane in any specific direction. Just turn at least one complete circle while in the calibration mode.

The answer to your question is in the very first post. The runway in question is located in Herlong California on a military ammo depot site.
