Site Identification of the GNSS Monument Site Name : U New Hampshire Four Character ID : NHUN Monument Inscription : IERS DOMES Number : (A9) CDP Number : (A4) Monument Description : MAST Height of the Monument : 7.5 m Monument Foundation : Side of building Foundation Depth : (m) Marker Description : Brass coupler Date Installed : 2004-08-27T00:00Z Geologic Characteristic : (BEDROCK/CLAY/CONGLOMERATE/GRAVEL/SAND/etc) Bedrock Type : (IGNEOUS/METAMORPHIC/SEDIMENTARY) Bedrock Condition : (FRESH/JOINTED/WEATHERED) Fracture Spacing : (1-10 cm/11-50 cm/51-200 cm/over 200 cm) Fault zones nearby : (YES/NO/Name of the zone) Distance/activity : (multiple lines) Additional Information : The antenna is on the northeast corner of a : concrete bldg attached to a ~2.6m tall mast. The : building is ~5m tall. The mast is attached via a : 90cm x30cm plate using six 5/8" bolts that : penetrate the entire 36cm thick wall to a : backing plate. The throughbolts hold the mast & : backing plate using double washers, including : double nuts that serve as spacers for the : external plate. A modified tribrach adaptor is : used as a levelling orienting plate such that : the mark is the invisible point formed by the : top horizontal surface of the brass coupler : and the vertical line through the middle of : the threaded part of the brass coupler 2.
