      DESCRIPTION OF DENVER BASE LINE
      YEAR MEASURED:  1976
      CHIEF OF PARTY:  MDC

      THE BASE LINE IS LOCATED IN WEST LAKEWOOD AT THE DENVER FEDERAL CENTER, IN THE NORTHEAST CORNER OF A CHAIN LINK FENCE THAT
      SURROUNDS THE DENVER FEDERAL CENTER ARMORY.

      THE FEDERAL CENTER IS THE MOST PROMINENT LANDMARK IN DENVER AND IS ON THE STATE MAP.  THEREFORE NO TO REACH HAS BEEN
      WRITTEN.

      THE 0 METER POINT, STAMPED 0 POINT 1976, IS A STANDARD NGS TRIANGULATION STATION DISK SET IN THE TOP OF A ROUND CONCRETE
      MONUMENT FLUSH WITH THE GROUND.  IT IS IN THE EXTREME NORTHEAST CORNER OF A CHAIN LINK FENCE THAT SURROUNDS THE ARMORY, 21
      FEET NORTHEAST OF AN 8-INCH EVERGREEN TREE, 11.5 FEET WEST OF A CHAIN LINK FENCE AND 9 FEET SOUTH OF A CHAIN LINK FENCE.

      THE BASE LINE CONSISTS OF THE 0, 150, 500, AND 1014 METER POINTS WITH A DISK SET AT 100 FEET FOR TAPE CALIBRATION.  THE
      BASE LINE IS AN EAST-WEST LINE WITH THE 0 METER POINT ON THE EAST END.  ALL THE MARKS ARE STANDARD NGS TRIANGULATION
      STATION DISKS SET IN THE TOP OF ROUND CONCRETE MONUMENTS FLUSH WITH THE GROUND.  THEY ARE STAMPED 0 POINT 1976, 150 POINT
      1976, 500 POINT 1976, AND 1014 POINT 1976.  THE 100 FOOT DISK HAS NO STAMPING ON IT AND THE TRIANGLE AND PUNCH HOLE HAS
      BEEN GROUND OFF.  A NEW PUNCH HOLE HAS BEEN MADE AT THIS TIME DENOTING 100.00 FEET.

      DESCRIPTION OF GOLDEN BASE LINE       ***  WARNING -  POOR MONUMENTS, CROSSES FAULT LINE  ***
      YEAR MEASURED:  1978 AND 1981
      CHIEF OF PARTY:  CWW

      ***WARNING NOTE***DESCRIPTION UPDATE-12/02/98-IT WAS REPORTED THAT THIS BASELINE HAS NEVER BEEN USED BECAUSE OF POOR
      MONUMENTS.  IT WAS ALSO DISCOVERED THAT THIS CBL CROSSES A FAULT LINE.  A DECISION WAS MADE TO REMOVE THIS BASELINE FROM
      THE CURRENT PUBLICATION.

      THIS BASE LINE WAS REMEASURED IN 1981, AND NO SIGNIFICANT CHANGES WERE NOTED.  THE JUNE 22, 1981 ADJUSTED DISTANCES ARE A
      COMBINATION OF THE 1978 AND 1981 MEASUREMENTS.

      THE BASE LINE IS LOCATED ABOUT 1.0 MILE SOUTH OF GOLDEN IN THE COLORADO SCHOOL OF MINES SURVEY FIELD, ON THE WEST SIDE OF
      UNITED STATES HIGHWAY 6, IN THE NORTHWEST 1/4 OF SECTION 3, TOWNSHIP 4 SOUTH, RANGE 70 WEST OF THE 6TH PRINCIPAL MERIDIAN
      JEFFERSON COUNTY, COLORADO.  A RADIO TRANSMITTER AND A RADAR FACILITY, WHICH ARE IN THE VICINITY OF THE BASE LINE, MAY
      INTERFERE WITH EDM OPERATIONS AND AFFECT THEIR RESULTS.

      TO REACH THE BASE LINE FROM THE UNITED STATES POST OFFICE ON 12TH STREET IN GOLDEN, GO WEST FOR 0.1 MILE TO WASHINGTON
      AVENUE.  TURN LEFT ON WASHINGTON AVENUE AND GO SOUTH FOR 0.5 MILE TO 19TH STREET.  TURN RIGHT ON 19TH STREET AND GO
      SOUTHWEST FOR 0.5 MILE TO THE JUNCTION WITH UNITED STATES HIGHWAY 6.  CONTINUE STRAIGHT AHEAD ON 19TH STREET FOR 0.1 MILE
      TO A SIDE ROAD LEFT AND THE JEFFERSON COUNTY SERVICE CENTER ON THE LEFT.  TURN LEFT AND GO SOUTH ON THE BLACKTOP, BEARING
      TO THE LEFT, FOR 0.1 MILE TO A LOCKED GATE (ADDRESS TO OBTAIN KEY BELOW) AND DIRT ROAD ON THE RIGHT.  TURN RIGHT, PASS
      THROUGH GATE AND GO SOUTH FOR 0.25 MILE TO ANOTHER GATE.  PASS THROUGH THIS GATE AND GO SOUTH ON THE TRACK ROAD ALONG THE
      POWER LINE FOR 0.05 MILE TO A FORK.  TAKE THE LEFT FORK AND CONTINUE SOUTH FOR 0.1 MILE.  HERE TURN LEFT AND GO EASTERLY
      ACROSS THE FIELD FOR 0.15 MILE TO THE HIGHEST PART OF THE RIDGE AND 0 METER POINT.

      THE 0 METER POINT IS 56.4 FEET WEST OF UTILITY POLE NUMBER 2765 AND 50.9 FEET WEST-SOUTHWEST OF A BARBED WIRE FENCE LINE.

      ALL OF THE SURFACE MARKS ARE COLORADO SCHOOL OF MINES DISKS SET IN 6-INCH ROUND CONCRETE POSTS THAT PROJECT ABOUT 4
      INCHES.  THEY ARE STAMPED WITH THEIR BASE LINE DESIGNATION AND THE YEAR 1977.  ALL OF THE POINTS HAVE UNDERGROUND MARKS
      WHICH ARE SET ABOUT 3.5 FEET BELOW THE SURFACE.

      THE BASE LINE IS A EAST-WEST LINE WITH THE 0 METER POINT ON THE EAST END.  IT IS MADE UP OF THE 0, 150, 600, AND 1000
      METER POINTS.  THE FROM AND TO STATION NAMES (THE METER POINT DESIGNATIONS) WERE PREASSIGNED AND DO NOT AGREE WITH THE
      MEASURED DISTANCES.  ALL OF THE MARKS ARE SET IN THE SURVEY FIELD, AND DUE TO ROCKY TERRAIN AND A RISE OF 272 FEET FROM
      THE 0 METER POINT TO THE 1000 METER POINT, IT IS ADVISABLE TO HAVE A TRUCK TO REACH ALL OF THE METER POINTS.

      THIS BASE LINE WAS ESTABLISHED IN CONJUNCTION WITH THE COLORADO SCHOOL OF MINES.  FOR FURTHER INFORMATION AND KEYS TO THE
      GATES, CONTACT MR. HARRY W. EMRICK, DIRECTOR OF CONTINUING EDUCATION, COLORADO SCHOOL OF MINES, GOLDEN, COLORADO  80401,

 SOUTHEAST ON THE GRAVEL ROAD, PASSING THROUGH THE GATE, FOR 0.03 KM (0.02 MI), THEN BEAR RIGHT AND GO SOUTH ACROSS THE PRAIRIE FOR
 0.6 KM (0.4 MI) TO THE 0 METER POINT ON THE RIGHT.

 THE BASE LINE IS A NORTH-SOUTH LINE WITH THE 0 METER POINT ON THE NORTH END. IT CONSISTS OF THE 0, 150, 430, AND 1400 METER POINTS.
 THE 150 AND 430 METER POINTS ARE OFFSET FROM THE LINE WITH THE 150 METER POINT WEST AND THE 430 METER POINT EAST OF THE LINE. THERE
 IS ALSO A DISK SET AT 100 FEET SOUTH OF THE 0 METER POINT TO BE USED FOR TAPE CALIBRATION, AND LOCATED IN LINE WITH THE 0 AND 1400
 METER POINTS. THE BASE LINE IS SET ON THE WEST SIDE OF THE LAMAR MUNICIPAL AIRPORT GROUNDS, ALONG COUNTY ROAD 3.

 THE 0 METER POINT IS A STANDARD NGS CALIBRATION BASE LINE DISK STAMPED "0 M 1988" SET INTO THE TOP OF AN 80 CM (31 IN) DIAMETER
 CONCRETE POST FLUSH WITH THE GROUND, 28.7 M (94.2 FT) EAST OF THE CENTERLINE OF COUNTY ROAD 3, 19.8 M (65.0 FT) EAST OF A BARBED
 WIRE FENCE, 1.3 M (4.3 FT) WEST OF A WITNESS POST, AND 1.3 M (4.3 FT) SOUTH OF A WITNESS POST.

 THE 150 METER POINT IS A STANDARD NGS CALIBRATION BASE LINE DISK STAMPED "150 M 1988" SET INTO THE TOP OF A 70 CM (28 IN) DIAMETER
 CONCRETE POST FLUSH WITH THE GROUND, 37.9 M (124.3 FT) NORTH OF THE NORTHEAST CORNER OF A METAL PUMP STATION, 25.3 M (83.0 FT) EAST
 OF THE CENTERLINE OF COUNTY ROAD 3, 16.4 M (53.8 FT) EAST OF A BARBED WIRE FENCE, 1.3 M (4.3 FT) EAST OF A WITNESS POST, AND 1.3 M
 (4.3 FT) NORTH OF A WITNESS POST.

 THE 430 METER POINT IS A STANDARD NGS CALIBRATION BASE LINE DISK STAMPED "430 M 1988" SET INTO THE TOP OF AN 80 CM (31 IN) DIAMETER
 CONCRETE POST FLUSH WITH THE GROUND, 30.6 M (100.4 FT) EAST OF THE CENTERLINE OF COUNTY ROAD 3, 21.7 M (71.2 FT) EAST OF A BARBED
 WIRE FENCE, 1.5 M (4.9 FT) NORTH OF A WITNESS POST, AND 1.4 M (4.6 FT) WEST OF A WITNESS POST.

 THE 1400 METER POINT IS A STANDARD NGS CALIBRATION BASE LINE DISK STAMPED "1400 M 1988" SET INTO THE TOP OF AN 80 CM (31 IN)
 DIAMETER CONCRETE POST FLUSH WITH THE GROUND, 39.8 M (130.6 FT) SOUTH OF THE SOUTHEAST CORNER OF A CINDER BLOCK PUMP STATION, 27.3 M
 (89.6 FT) EAST OF THE CENTERLINE OF COUNTY ROAD 3, 18.4 M (60.4 FT) EAST OF A BARBED WIRE FENCE, 1.45 M (4.6 FT) NORTH OF A WITNESS
 POST, AND 1.3 M (4.3 FT) EAST OF A WITNESS POST.

 THE 100-FOOT POINT IS A STANDARD NGS CALIBRATION BASE LINE TAPING DISK STAMPED "100 FT 1988" SET INTO THE TOP OF A 60 CM (24 IN)
 DIAMETER CONCRETE POST FLUSH WITH THE GROUND, 28.7 M (94.2 FT) EAST OF THE CENTERLINE OF COUNTY ROAD 3, 19.8 M (65.0 FT) EAST OF A
 BARBED WIRE FENCE, AND 1.0 M (3.3 FT) EAST OF A WITNESS POST.

 USER NOTES: CBL USERS SHOULD TAKE CARE IN PLUMBING OVER ALL POINTS. ELEVATIONS ARE FOR CBL USE ONLY. THE LAMAR MUNICIPAL AIRPORT
 MANAGER SHOULD BE CONTACTED BEFORE CBL USE, TEL.(719) 336-9665. NOTE: THE 150 AND 430 METER POINTS ARE SET OFF LINE AND HORIZONTAL
 DIRECTIONS FROM THE LINE TO THESE POINTS ARE NEEDED TO REDUCE MEASUREMENTS BACK TO THE LINE.

 THIS BASE LINE WAS ESTABLISHED IN CONJUNCTION WITH THE COLORADO DEPARTMENT OF HIGHWAYS, AND THE CITY OF LAMAR, COLORADO. FOR MORE

 ALL OF THE MARKS ARE STANDARD CALIBRATION BASE LINE DISKS SET IN THE TOP OF 0.3 METER DIAMETER ROUND CONCRETE MONUMENTS THAT ARE
 FLUSH WITH THE GROUND.  THE DISKS ARE STAMPED 1979 AND IDENTIFIED TO THE NEAREST METER.

 THE BASE LINE IS AN EAST-WEST LINE WITH THE 0 METER POINT AT THE WEST END.  THE BASE LINE IS MADE UP OF 0, 150, 430, AND 1400 METER
 POINTS, WITH A POINT FOR THE CALIBRATION OF 100 FOOT TAPES SET ON LINE EAST OF THE 0 METER POINT.

 THE BASE LINE WAS ESTABLISHED IN CONJUNCTION WITH THE COLORADO STATE HIGHWAY DEPARTMENT, MESA COUNTY SURVEYOR'S OFFICE, AND THE UTE
