Form Prepared by (full name) : Michael Schmidt Date Prepared : 29-SEP-1999 Report Type : UPDATE Prepared Using : 1. Site Identification of the GPS Monument Site Name : Williams Lake Four Character ID : WILL Monument Inscription : 937011 IERS DOMES Number : 40134M001 CDP Number : Date Installed : 06-OCT-1993 19:03 UT Geologic Characteristic : BEDROCK Bedrock Type : GRANULAR VOLCANIC CONGLOMERATE Bedrock Condition : WEATHERED Fracture Spacing : 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 : 26-NOV-97:: : ******************************************** : 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 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 3.0 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. The : antenna and choke ring asembly are protected : by a dome. 2. Site Location Information City or Town : Williams Lake State or Province : B.C.
