 OA0894.The horizontal coordinates were established by classical geodetic methods
 OA0894.and adjusted by the National Geodetic Survey in October 1991.
 OA0894
 OA0894.The NAVD 88 height was computed by applying the VERTCON shift value to
 OA0894.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 OA0894.The vertical order pertains to the NGVD 29 superseded value.
 OA0894
 OA0894.The Laplace correction was computed from USDV2009 derived deflections.
 OA0894
 OA0894.The geoid height was determined by GEOID09.

 OA0894
 OA0894'DESCRIBED BY COAST AND GEODETIC SURVEY 1942 (JCS)
 OA0894'STATION IS ON A ROCKY LEDGE ON THE SUMMIT OF IRON MOUNTAIN AND ON
 OA0894'THE SAME MOUNTAIN AS THE FOREST SERVICE LOOKOUT HOUSE.  A HIGHER BUT
 OA0894'TIMBERED PORTION OF THE MAIN MOUNTAIN LIES NORTHWARD FROM THE
 OA0894'STATION.  STATION IS ABOUT 9 MILES, AIR LINE, NW OF AGNESS, 27
 OA0894'MILES S OF MYRTLE POINT, 9 MILES SW OF CHINA FLATS, AND 23 MILES
 OA0894'NW OF GOLD BEACH.
 OA0894'
 OA0894'STATION IS A BRONZE DISK SET IN A DRILL HOLE IN A ROCK OUTCROPPING
 OA0894'FLUSH WITH THE GROUND, STAMPED IRON 1942.  LOCATED ON THE CREST
 OA0894'OF THE SHARP RIDGE JUST N OF THE IRON MOUNTAIN LOOKOUT HOUSE.
 OA0894'
 OA0894'NO UNDERGROUND MARK WAS ESTABLISHED.
 OA0894'
 OA0894'REFERENCE MARK NO.1 IS A BRONZE DISK SET IN A DRILL HOLE IN A
 OA0894'ROCK OUTCROPPING FLUSH WITH THE GROUND, STAMPED IRON NO.1
 OA0894'1942.  MARK IS 2 FEET HIGHER THAN THE STATION MARK.
 OA0894'
 OA0894'REFERENCE MARK NO.2 IS A BRONZE DISK SET IN A DRILL HOLE IN A
 OA0894'ROCK OUTCROPPING FLUSH WITH THE GROUND, STAMPED IRON NO.2
 OA0894'1942.  MARK IS 2 FEET HIGHER THAN THE STATION MARK.
 OA0894'
 OA0894'AZIMUTH MARK IS A BRONZE DISK SET IN A DRILL HOLE IN AN
 OA0894'OUTCROPPING BEDROCK, STAMPED IRON 1942.  MARK IS 3.6 MILES FROM
 OA0894'POINT ON THE ROAD TO THE STATION MARKED BY A SIGN MIDDLE ELK
 OA0894'ROAD.  MARK IS LOCATED IN A LARGE ROCK OUTCROPPING TO THE RIGHT
 OA0894'SIDE OR N OF THE ROAD IMMEDIATELY OPPOSITE A HOUSE TO THE LEFT
 OA0894'OF THE ROAD.  ROCK OUTCROPPING IS ABOUT 20 FEET HIGHER THAN THE
 OA0894'ROAD, ABOUT 20 FEET N OF THE CENTER LINE OF THE ROAD, AND IS
 OA0894'ABOUT 2 MILES AIR LINE E OF THE STATION.
 OA0894'
 OA0894'REACHED FROM THE POST OFFICE IN POWERS BY FOLLOWING THE AGNESS
 OA0894'ROAD S FOR 11.4 MILES TO CHINA FLATS.  CONTINUE S ON THE
 OA0894'MAIN-TRAVELED ROAD FOR 6.75 MILES TO FORKS.  TAKE THE RIGHT FORK,
 OA0894'THE AGNESS ROAD, FOR 4.7 MILES TO FORKS AT THE SUMMIT AND SIGN
 OA0894'AGNESS 13, POWERS R.S. 22.  TAKE THE RIGHT FORK, THE MIDDLE ELK
 OA0894'ROAD, WESTERLY FOR 6.1 MILES TO TRAIL SIGNS.  THENCE CONTINUE
 OA0894'0.2 MILE TO FORKS.  TAKE THE RIGHT FORK UPGRADE 0.05 MILE TO
 OA0894'C.C.C. CAMP AND THE END OF TRUCK TRAVEL.  FROM THIS POINT
 OA0894'FOLLOW A ROUGH, NEWLY GRADED ROAD-TRAIL NORTHERLY AROUND HILLSIDE
 OA0894'TO SADDLE.  THENCE CONTINUE ON TRAIL UP RIDGE NORTHERLY TO
 OA0894'THE IRON MOUNTAIN LOOKOUT AND THE STATION.
