RY0856.The horizontal coordinates were established by classical geodetic methods
RY0856.and adjusted by the National Geodetic Survey in July 1992.
RY0856.
RY0856.The NAVD 88 height was computed by applying the VERTCON shift value to
RY0856.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
RY0856
RY0856.Significant digits in the geoid height do not necessarily reflect accuracy.

RY0856 STATION DESCRIPTION
RY0856
RY0856'DESCRIBED BY COAST AND GEODETIC SURVEY 1934 (EBL)
RY0856'ON PETTY MOUNTAIN ABOUT 6 MILES, AIRLINE, SOUTH BY EAST OF THE
RY0856'TOWN OF ALBERTON, ON U.S. HIGHWAY 10, ON THE RIDGE EAST OF
RY0856'PETTY CREEK, 56.6 FEET SOUTHEAST OF A LOOKOUT HOUSE.
RY0856'
RY0856'TO REACH FROM ALBERTON GO ON THE GRAVELED ROAD WHICH CROSSES
RY0856'THE RAILROAD TRACKS EAST OF THE RAILROAD DEPOT, FOLLOW THIS
RY0856'ROAD 1.7 MILES, TURN RIGHT AFTER CROSSING THE BRIDGE AND
RY0856'RAILROAD TRACKS AND GO 0.1 MILE, TURN LEFT, GO 2.3 MILES,
RY0856'KEEP STRAIGHT AHEAD, OR RIGHT, FOR 9.1 MILES TO A RANCH ON THE
RY0856'RIGHT AND A SMALL CLEARING ON THE LEFT, WHICH IS ON THE RIGHT
RY0856'SIDE OF A SMALL CREEK. THE U.S. FOREST SERVICE TRAIL TAKES
RY0856'OFF ABOUT 100 YARDS FROM THE ROAD AND FOLLOWS THE RIDGE TO
RY0856'THE NORTH OF THE CLEARING, FOLLOW THIS (PRINTERS CREEK) TRAIL
RY0856'4.5 MILES TO THE JUNCTION OF THE GRAVE RANGE TRAIL ON TOP OF
RY0856'THE RIDGE, TAKE THE TRAIL TO THE LEFT 1.5 MILES TO THE
RY0856'PETTY LOOKOUT. IT IS 6 MILES BY TRAIL AND ABOUT 4 HOURS
RY0856'WITH A HEAVY PACK.
RY0856'
RY0856'SURFACE AND REFERENCE MARKS ARE STANDARD BRONZE DISKS SET
RY0856'IN BOULDERS AS DESCRIBED IN NOTES 4 AND 12C RESPECTIVELY.

RY0856 STATION RECOVERY (1935)
RY0856
RY0856'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1935 (EBL)
RY0856'STATION WAS FOUND AS PREVIOUSLY DESCRIBED AND IN GOOD CONDITION,
RY0856'EXCEPT THAT REFERENCE MARK NO. 2 HAS BEEN DESTROYED. A NEW
RY0856'45-FOOT LOOKOUT TOWER IS NEARING COMPLETION AND MUCH EXCAVATING
RY0856'HAS BEEN DONE. REFERENCE MARK NO. 1 IS A FEW FEET WEST OF THE
RY0856'NEW LOOKOUT TOWER AND ABOUT 18 INCHES FROM A LARGE DITCH THAT
RY0856'HAS BEEN DUG AROUND THE NEW TOWER. THERE IS A POSSIBILITY
RY0856'THAT IT WILL BE DISTURBED.

RY0856'
RY0856'THE ROUTE DESCRIPTON BY E.B.L. IN 1934 AND 1935 IS ADEQUATE WITH
RY0856'THE FOLLOWING EXCEPTIONS - - THE LOOKOUT TOWER HAS BEEN CUT DOWN
RY0856'AND BOTH IT AND THE LOOKOUT CABIN DESTROYED BY FIRE. REFERENCE
RY0856'MARK NO. 1 WAS SEARCHED FOR BUT NOT FOUND. REACHED BY HELICOPTER.
