WIDC Site Information Form Southern California Integrated GPS Network 0. Form Prepared by (full name) : Paul F. Jamason Date Prepared : 22-DEC-1998 Report Type : UPDATE Prepared Using : 1. Site Identification of the GPS Monument Site Name : Wide Canyon Four Character ID : WIDC Monument Inscription : None IERS DOMES Number : 49917M001 CDP Number : not available Date Installed : 30-SEP-1997 00:43 UT Geologic Characteristic : BEDROCK Bedrock Type : METAMORPHIC Bedrock Condition : FRESH Fracture Spacing : () Notes : () Additional Information : SCIGN - Southern California Integrated GPS : Network. The monument is composed of four 1" diameter stainless steel rods in a tripod-with-vertical-rod configuration. The rods are grouted into solid meta-sediment at 5-6' depths and are welded together approximately 3' above ground level. This site empolys a SCIGN antenna adaptor with specified fixed antenna height of 0.0083 m. Verical datum is the raised nipple on the lower part of the antenna adaptor. A drilled divot mark on the north-facing tripod leg is still to be performed for a secondary measurement. 2.
