Site Identification of the GNSS Monument Site Name : Ucluelet Four Character ID : UCLU Monument Inscription : 947001 IERS DOMES Number : 40140M001 CDP Number : (A4) Monument Description : CONCRETE PIER, 56cm DIAMETER Height of the Monument : 1.5m Monument Foundation : RE-ENFORCED STEEL IN BEDROCK Foundation Depth : 1m Marker Description : BRASS PLATE; FORCED CENTER STAINLESS STEEL : BOLT Date Installed : 1994-05-05 Geologic Characteristic : BEDROCK Bedrock Type : METAMORPHIC Bedrock Condition : WEATHERED Fracture Spacing : 0 - 50cm Fault zones nearby : Cascadia Subduction Zone Distance/activity : (multiple lines) Additional Information : This station is part of the Western Canada : Deformation Array (WCDA) as well as the : Canadian Active Control System (CACS). : ******************************************** : The GPS reference mark consists of a brass : plate with a forced centered stainless steel : bolt. The brass plate is embedded on top : of a 1.5 metre high concrete pier, 56 cm : in diameter. The concrete pier is anchored : to exposed bedrock using steel : re-enforcement bars to a depth of : 1.0 m. The antenna is attached to the brass : forced centered plate via a 10 cm high : anodized aluminum base. : This base provides a constant height above : the brass plate and also permits : the antenna to be referenced to north. : 2.
