RD3836
RD3836''DESCRIBED BY COAST AND GEODETIC SURVEY 1878 (CR)
RD3836''STATION IS ABOUT 1-1/2 MILES BELOW COLUMBIA CITY, NEARLY OPPOSITE
RD3836''THE HEAD OF DEER ISLAND, ON THE SUMMIT OF A WOODED HILL ABOUT 460
RD3836''FEET ABOVE THE RIVER LEVEL.  THE STATION IS MARKED 2-1/2 FEET
RD3836''UNDERGROUND BY A DRILL HOLE FILLED WITH LEAD IN A FLAT-TOPPED
RD3836''STONE, AND AT THE SURFACE BY A SIMILAR MARK IN A STONE PROJECTING
RD3836''6 INCHES ABOVE THE SURFACE.  THREE STAKES WERE SET AS FOLLOWS--N
RD3836''1.79 METERS, S AND E EACH 1.83 METERS.  THERE ARE THREE COPPER
RD3836''TACKS IN A TRIANGULAR BLAZE ON A FIR TREE BEARING S 15 DEG W
RD3836''MAGNETIC, DISTANT 2.35 METERS.

RD3836
RD3836''RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1934 (LCJ)
RD3836''STATION NOT RECOVERED.  STATION SITE WAS FOUND BUT NO TRACE OF ANY
RD3836''MARKS.  THE SPACE WAS HEAVILY OVERGROWN WITH SECOND-GROWTH TIMBER,
RD3836''ALSO HAD BEEN BURNED OVER.  THE STATION WAS ALSO SEARCHED FOR BY
RD3836''A PARTY OF THREE MEMBERS OF THE TRIANGULATION PARTY, WITHOUT
RD3836''RESULT.  IT IS HIGHLY POSSIBLE THAT THE FALLING OF TREE COULD
RD3836''EASILY TEAR THE SURFACE MARK OUT.

RD3836''STATION RECOVERED AS DESCRIBED.
RD3836''
RD3836''A NEW STATION, MAPLE HILL 2 1937, WAS ESTABLISHED IN THIS
RD3836''VICINITY.  IT IS 43.108 METERS DISTANT IN AZIMUTH 251 DEG 11 MIN
RD3836''24 SEC.

RD3836''RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1952 (GEB)
RD3836''THE STATION WAS RECOVERED AS DESCRIBED BY R.W.K. IN 1937.
RD3836''
RD3836''THE STATION IS ABOUT 1-1/2 MILES NORTHWEST OF COLUMBIA CITY, 1.6
RD3836''MILES SOUTHEAST OF THE STORE AT DEER ISLAND, AND 0.4 MILE SOUTHWEST
RD3836''OF U.S. HIGHWAY 30.  IT IS ABOUT 50 METERS SOUTHWEST OF THE BROW
RD3836''OF A TIMBERED HILL THAT EXTENDS NORTHEAST FROM THE MAIN RIDGE.
RD3836''THE HILL IS ABOUT 420 FEET IN ELEVATION, AND FROM THE HIGHWAY
RD3836''APPEARS TO BE ABOUT 3/4 THE ELEVATION OF THE SKYLINE.  LOOKING
RD3836''WEST FROM THE HIGHWAY THE HILL IS NOT EASILY DISCERNIBLE, BEING
RD3836''BACKGROUNDED BY THE HIGHER RIDGE TO THE SOUTHWEST.
RD3836''
RD3836''THE STATION MARK IS A LEAD PLUG IN A DRILL HOLE IN A 6-INCH BY
RD3836''8-INCH BOULDER THAT IS FLUSH WITH THE SURFACE OF THE GROUND.  IT
RD3836''IS 43.108 METERS SOUTHWEST OF STATION MAPLE HILL 2, 12.9 METERS
RD3836''NORTHWEST OF THE SOUTHERLY OF TWO 18-INCH FIRS, 11.5 METERS
RD3836''WEST-NORTHWEST OF THE NORTHERLY ONE, 11.3 METERS NORTHEAST OF A
RD3836''2-FOOT FIR WITH A LARGE BLAZE AT ITS BASE, AND 2-1/2 FEET NORTH
RD3836''OF A CLUMP OF ALDER.
RD3836''
RD3836''TO REACH THE STATION FROM THE CITY LIMIT SIGN AT THE NORTH EDGE
RD3836''OF COLUMBIA CITY GO NORTHERLY ON U.S. HIGHWAY 30 FOR 1.55 MILES TO
