That would be the "big radar" facility NW of the lakebed. This is
supposedly a large rotating antenna, and it does show up on most maps and
overhead photos (though I have yet to see anything with decent detail). One
of the currrent theories is that this is associated with a system for
in-flight radar cross section measurement- which would explain the beacon.
You'd want to use it somewhat like a waypoint or VOR to home in on from
various directions to get RCS measurements from different angles, speeds,
etc.
