Additional Information : The GPS Reference Mark consists of a 3"steel
: tubing 1.22m long mast that is permanently
: anchored to a concrete block building. UNAVCO
: square leveling device is utilized. This mast is
: permanently anchored to the building by means of
: steel plate welded to the mast with holes that
: allow anchoring bolts to pass completely through
: the wall to another 1/2 steel plate. The anchor
: bolts pass completely through the wall and are
: secured with locking nuts at the ends on each
: side of the wall.
