WILL Site Information Form International GPS Service for Geodynamics 0. Form Prepared by (full name) : Michael Schmidt Date Prepared : 15-JAN-1998 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 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 : 3.0 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. 2.
