 OA1141.The horizontal coordinates were established by classical geodetic methods
 OA1141.and adjusted by the National Geodetic Survey in October 1991.

 OA1141.The NAVD 88 height was computed by applying the VERTCON shift value to
 OA1141.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 OA1141.The vertical order pertains to the NGVD 29 superseded value.
 OA1141
 OA1141.The Laplace correction was computed from DEFLEC09 derived deflections.
 OA1141
 OA1141.The geoid height was determined by GEOID09.

 OA1141
 OA1141'DESCRIBED BY US GEOLOGICAL SURVEY 1942 (JCS)
 OA1141'STATION IS ON THE SUMMIT OF TRAIL BUTTE, ABOUT 13 MILES, AIR
 OA1141'LINE, NE OF MARSHFIELD AND ABOUT 5 MILES N OF ALLEGANY.  IT IS
 OA1141'NEAR THE SE CORNER OF TRAIL BUTTE LOOKOUT TOWER, SET IN A DRILL
 OA1141'HOLE IN A SMALL BOULDER AND IS STAMPED TRAIL BUTTE 2, 1942.  THE
 OA1141'ELEVATION OF THE MARK IS 1645 FEET.
 OA1141'
 OA1141'TO REACH THE STATION FROM THE ALLEGANY POST OFFICE AND STORE, GO
 OA1141'N ON A GRADED ROAD, UP THE WEST FORK OF THE MILLICOMA RIVER, AT
 OA1141'SIGN DEAN MTN. 25 MILES, FOR 5 MILES TO A POINT ABOUT 0.4 MILE
 OA1141'ABOVE THE RIVER BRIDGE.  TAKE CATERPILLAR ROAD LEFT, W, FOR 2.0
 OA1141'MILES TO THE TOP OF THE MOUNTAIN AND THE STATION.
 OA1141'
 OA1141'ALL OBSERVATIONS WERE MADE FROM TRAIL BUTTE 2, U.S.C. AND
 OA1141'G.S. R.M. NO.1 AND ALL HORIZONTAL ANGLES WERE REDUCED TO TRAIL
 OA1141'BUTTE 2, U.S.G.S.

 OA1141
 OA1141'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1952 (CTH)
 OA1141'THE STATION AND A USGS MARK WERE RECOVERED IN GOOD
 OA1141'CONDITION.  R.M. NO. 1 WAS SEARCHED FOR BUT COULD NOT BE FOUND.  IT
 OA1141'IS BELIEVED TO HAVE BEEN DESTROYED.  A DILIGENT SEARCH WAS MADE
 OA1141'FOR THE REFERENCE MARK.
 OA1141'
 OA1141'TO REACH THE STATION FROM THE STORE AND P.O. IN ALLEGANY, GO NW
 OA1141'UP THE WEST FORK MILLICOMA RIVER FOR 5.25 MILES TO A SIDE ROAD
 OA1141'LEFT AT A SIGN TRAIL BUTTE 2 6/10.  TURN LEFT (NE) THRU A GATE
 OA1141'AND CONTINUE UP THE MOUNTAIN N FOR 0.05 MILE TO 3 FORKS.  TAKE
 OA1141'THE CENTER FORK NE UPHILL AND FOLLOW ROAD 2.5 MILES TO THE
 OA1141'LOOKOUT HOUSE AND STATION.
