No launch site, this was just a massive radar installation on the west peak
of the mountain.
It's still in use by the FAA.
The barracks and most of the housing on the west peak were demolished
a few years ago.
Access: shortly before the road up Mt. Tam gets to the top, there's a
big gate on the north side.
