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.
