1.   Site Identification of the GPS Monument

     Site Name                : Whistler
     Four Character ID        : WSLR
     Monument Inscription     : 967000
     IERS DOMES Number        : 40141M001
     CDP Number               :
     Date Installed           : 12-SEP-1996
     Geologic Characteristic  : BEDROCK
       Bedrock Type           : METAMORPHIC
       Bedrock Condition      : WEATHERED
       Fracture Spacing       : 50 - 100cm
       Notes                  :
     Additional Information   : This station is part of the Western Canada
                              : Deformation Array (WCDA) as well as the Canadian
                              : Active Control System (CACS). The following
                              : information is current as of 15-DEC-97:
                              : ************************************************
                              : The GPS reference mark consists of a brass plate
                              : with a forced centred stainless steel bolt. The
                              : brass plate is embedded on top of a 3.0 metre
                              : high concrete pier, 60 cm in diameter. The
                              : concrete pier is anchored to exposed bedrock
                              : using steel re-enforcement bars to a depth of
                              : 1.5 m. The antenna is attached to the brass
                              : forced centred 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. The
                              : antenna and choke ring asembly are protected by
                              : an acrylic dome. The dome was installed using an
                              : aluminum flange ring attached to the choke ring.
                              : The flange ring extends the radius of the ground
                              : plane by 2.5 cm.
