Site Identification of the GNSS Monument Site Name : PABH_PNGA_WA1997 Four Character ID : PABH Monument Inscription : IERS DOMES Number : 49768M001 CDP Number : (A4) Monument Description : DEEP DRILLED-BRACED Height of the Monument : (m) Monument Foundation : UNKNOWN Foundation Depth : (m) Marker Description : UNKNOWN Date Installed : 1997-08-30 Geologic Characteristic : UNCONSOLIDATED Bedrock Type : Unconsolidated sediments 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 : Monument is "drilled braced monument" : constructed by EarthSafe. A vertical 5cm : galvanized schedule 80 pipe is set into a 12m : deep hole. Four addtl galvanized pipes are set : into holes drilled 30 deg fromo vertical. The : four angled pipes meet, and are welded to the : central pipe apprx 2m above the ground surface. : The drill holes are filled with non-shrink grout : to within apprx 3m of the surface; the upper : portion of the drill holes are filled with foam : to isolate the pipes from near-surface ground : movement. The "mark" is a punch in the center of : a S/S disk attached to the top of the central : pipe. The JPL-designed ant mount incorporates a : spike of fixed length and a leveling mechanism. 2.
