 BN0699
 BN0699'DESCRIBED BY COAST AND GEODETIC SURVEY 1956 (WFD)
 BN0699'THE STATION IS LOCATED ON THE SUMMIT OF A MOUNTAIN KNOWN AS
 BN0699'THE ENCHANTED ROCK, ABOUT 18-1/2 MILES SOUTH-SOUTHWEST OF
 BN0699'LLANO, 16-1/2 MILES NORTH-NORTHEAST OF FREDERICKSBURG, 1/2
 BN0699'MILE NORTH OF THE LLANO-GILLESPIE COUNTY LINE, AND ON LAND
 BN0699'OWNED BY MR. CHARLEY MOSS.
 BN0699'
 BN0699'TO REACH THE STATION FROM THE JUNCTION OF U.S. HIGHWAY 87 AND
 BN0699'FARM ROAD 965 IN FREDERICKSBURG, GO NORTH ON FARM ROAD 965
 BN0699'FOR 10.5 MILES TO A SIDE ROAD ON THE LEFT, CONTINUE STRAIGHT
 BN0699'AHEAD ON THE MAIN TRAVELED ROAD FOR 1.6 MILES TO A SIDE ROAD
 BN0699'ON THE LEFT AND SIGN ENCHANTED ROCK, TURN LEFT AND FOLLOW THE
 BN0699'MAIN ROAD FOR 3.75 MILES TO A CATTLE GUARD, AND THE AZIMUTH
 BN0699'MARK AS DESCRIBED BELOW, CONTINUE ON THE MAIN ROAD FOR 0.8
 BN0699'MILE TO MR. MOSS HOME ON THE LEFT, CONTINUE FOR 0.05 MILE
 BN0699'TO SIDE ROAD LEFT INTO PARK, TURN LEFT AND FOLLOW ROAD 0.2
 BN0699'MILE TO SOUTH END OF PARK AND SIGN MAIN TRAIL, FOLLOW THE
 BN0699'PAINTED ARROWS ON ROCK TO THE SUMMIT AND STATION.  NOTE--A
 BN0699'FOUR WHEEL DRIVE TRUCK IS NEEDED TO DRIVE FROM MR. MOSS
 BN0699'HOME TO THE TOP OF THE MOUNTAIN.
 BN0699'
 BN0699'THE STATION MARK IS FLUSH WITH THE SURFACE OF THE BEDROCK,
 BN0699'AND THE DISK IS STAMPED ENCHANTED ROCK 1956.
 BN0699'
 BN0699'REFERENCE MARK NO 1 IS FLUSH WITH THE SURFACE OF THE BEDROCK,
 BN0699'AND THE DISK IS STAMPED ENCHANTED ROCK NO 1 1956.
 BN0699'
 BN0699'REFERENCE MARK NO 2 IS FLUSH WITH THE SURFACE OF THE BEDROCK,
 BN0699'AND THE DISK IS STAMPED ENCHANTED ROCK NO 2 1956.
 BN0699'
 BN0699'THE AZIMUTH MARK IS 115 FEET NORTH OF THE CATTLE GUARD, 18
 BN0699'FEET SOUTH OF THE CENTER OF THE MAIN ROAD, AND 3 FEET NORTHWEST
 BN0699'OF A WHITE 4 IN X 4 IN WITNESS POST.  THE MARK IS FLUSH WITH
 BN0699'THE SURFACE OF A SMALL BOULDER THAT PROTRUDES ABOUT 24 INCHES.
 BN0699'THE DISK IS STAMPED ENCHANTED ROCK 1956.

 BN0699
 BN0699'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1959 (WCR)
 BN0699'THE STATION, REFERENCE MARKS AND THE AZIMUTH MARK WERE ALL
 BN0699'RECOVERED IN GOOD CONDITION AS DESCRIBED.  THE ROUTE TO THE
 BN0699'STATION, STATE HIGHWAY NO. 965 WAS UNDER CONSTRUCTION IN
 BN0699'1959 AND WAS BEING SURFACED TO THE ENCHANTED ROCK STATE PARK
 BN0699'AT THE BASE OF THE TRAIL TO THE STATION AND THE 1956 AZIMUTH
 BN0699'MARK WAS IN THE CONSTRUCTION AREA.  A NEW AZIMUTH MARK WAS
 BN0699'SET AND THE ORIGINAL AZIMUTH MARK WAS REMOVED.
 BN0699'
 BN0699'THE AZIMUTH MARK IS AS FOLLOWS.  A STANDARD AZIMUTH DISK
 BN0699'SET IN BEDROCK AT THE TOP OF A ROCKY DIVIDE ABOUT 100
 BN0699'YARDS EAST OF THE HIGHWAY WHICH IS ABOUT 30 FEET HIGHER
 BN0699'THAN THE HIGHWAY.  IT IS ABOUT 50 FEET NORTH OF A FENCE LINE
 BN0699'CROSSING THE DIVIDE AND ON THE NORTHWEST SLOPE OF THE ROCK AND
 BN0699'ABOUT 1 FOOT LOWER THAN THE HIGHEST POINT OF THE ROCK.  IT
 BN0699'IS ABOUT 100 YARDS EAST OF A CATTLE GUARD AND 0.75 MILE SOUTH
 BN0699'OF THE STATION.

 BN0699                          STATION RECOVERY (2006)
 BN0699
 BN0699'RECOVERY NOTE BY US POWER SQUADRON 2006 (RBP)
 BN0699'THE DISK IS MISSING FROM THE STATION MARK, BUT THE LOCATION STILL HAS
 BN0699'THE DRILL HOLE AND REMNANTS OF THE DISK MOUNTING.  REFERENCE MARK
 BN0699'NUMBER 1 IS IN A SIMILAR CONDITION.  REFERENCE MARK NUMBER 2 IS IN
 BN0699'GOOD CONDITION AND CAN BE USED TO LOCATE THE STATION MARK, WHICH IS
 BN0699'APPROXIMATELY 30 FEET NORTH-NORTHEAST.
 BN0699'THE REMNANTS OF REFERENCE MARK NUMBER 2 ARE APPROXIMATELY 25 FEET EAST
 BN0699'OF THE STATION MARK.
 BN0699'TO REACH THE STATION FROM THE INTERSECTION OF HIGHWAY 87 AND FARM ROAD
 BN0699'965 IN FREDERICKSBURG, GO NORTH ON FARM ROAD 965 ABOUT 17 MILES TO THE
 BN0699'ENTRANCE OF ENCHANTED ROCK STATE NATURAL AREA.  A STEEP HIKING TRAIL
 BN0699'LEADS TO THE TOP OF ENCHANTED ROCK, APPROXIMATELY 3/4 MILE NORTH OF
 BN0699'THE PARK OFFICE.  THE STATION AND REFERENCE MARKS ARE AT THE HIGHEST
 BN0699'POINT.
