Site Identification of the GPS Monument Site Name : Briones Reservoir Four Character ID : BRIB Monument Inscription : none IERS DOMES Number : none CDP Number : none Date Installed : 06-Aug-1993 00:00 UT Geologic Characteristic : BEDROCK Bedrock Type : SEDIMENTARY Bedrock Condition : (FRESH/JOINTED/WEATHERED) Fracture Spacing : (1-10 cm/10-50 cm/50-200 cm/over 200 cm) Notes : Current monument, installed 24-MAR-2000, is poured concrete cylinder with continuous steel reinforcement to older monument. Reference point is mark on SCIGN adaptor. Original monument, valid 06-Aug-1993 to 23-MAR-2000, was drilled and cemented into massive sandstone outcrop. Threaded 5/8" rod cemented about 0.8m deep into rock with stainless steel collar at surface. Antenna threaded onto rod in reproducible manner. Mark was top center of rod.
