Klamath Falls NGS Calibration Baseline 0 Meter Point Disk - Klamath Falls, OR - U.S. Benchmarks on Waymarking.com

I recovered this National Geodetic Survey Calibration Baseline 0 meter point disk from 1986 in good condition. It's monumented in a square concrete pad and underneath a metal access cover. There are three metal witness posts near the disk that aid in recovery.

This disk is the first of four calibration baseline disks along this dirt road paralleling Lost River Diversion Canal. Access to these calibration disks is through a metal entry gate and mentions it being on private property, so do so at your own risk.

DESCRIPTION OF KLAMATH FALLS BASE LINE
YEAR MEASURED: 1987
YEAR REMEASURED: 2001
LATITUDE: 42 08 26
LONGITUDE: 121 43 02
AZIMUTH: 090
CHIEF OF PARTY: CLS

THIS BASE LINE IS LOCATED 4.8 KM (3.0 MI) SOUTHEAST OF KLAMATH FALLS, JUST EAST OF THE SOUTHEAST CORNER OF THE KLAMATH FALLS AIRPORT, AND ALONG THE SOUTH EDGE OF THE LOST RIVER DIVERSION CHANNEL CANAL ACCESS ROAD.

THIS BASE LINE IS A WEST-EAST LINE WITH THE 0 METER POINT AT THE WEST END. THE CBL CONSISTS OF THE 0, 150, 430, AND 1270 METER POINTS. ALL POINTS ARE SET ON A LINE WHICH RUNS PARALLEL AND ALONG THE SOUTH EDGE OF THE LOST RIVER DIVERSION CHANNEL CANAL.

TO REACH THE BASE LINE FROM THE JUNCTION OF U.S. ROUTE 97 AND STATE ROUTE 140, GO EAST ON STATE ROUTE 140 (SOUTH SIDE EXPRESSWAY) FOR 4.5 KM (2.8 MI) TO AN INTERSECTION, WASHBURN ROAD. CONTINUE STRAIGHT AND GO EAST FOR 3.4 KM (2.1 MI) TO AN INTERSECTION, HOMEDALE ROAD. TURN RIGHT AND GO SOUTH FOR 1.2 KM (0.75 MI) TO A RAILROAD CROSSING. CONTINUE SOUTH FOR 1.3 KM (0.8 MI) TO A BEND LEFT. FOLLOW THE BEND (HENLEY ROAD) AN GO EAST FOR 0.4 KM (0.25 MI) TO A SIDE ROAD RIGHT, THE CONTINUATION OF HOMEDALE ROAD. TURN RIGHT AND GO SOUTH FOR 1.2 KM (0.75 MI) TO A CANAL BRIDGE AND THE ENTRANCE TO A DIRT ROAD ALONG THE SOUTH SIDE OF THE CANAL ON THE LEFT. TURN LEFT AND GO EAST FOR 68.3 METERS (224 FT) TO THE 0 METER POINT ON THE RIGHT.

THE 0 METER POINT IS A STANDARD NGS CALIBRATION BASE LINE DISK, STAMPED "0 1986", SET IN THE TOP OF A 45 CM (18 IN) DIAMETER CONCRETE POST 20 CM (8 IN) BELOW THE SURFACE OF THE GROUND AND COVERED BY A WOOD BOX. IT IS: 1.0 M (3.3 FT) NORTH OF A WITNESS POST, 2.3 M (7.5 FT) SOUTH OF THE DIRT ROAD CENTERLINE, AND 45.0 M (147.6 FT) EAST OF A METAL GATE.
