LV0930 STATION DESCRIPTION
LV0930
LV0930'DESCRIBED BY COAST AND GEODETIC SURVEY 1919 (EBL)[E.B. Latham]
LV0930'STATION IS ABOUT 4 MILES FROM SCOTIA, ON TOP OF THE MOUNTAIN
LV0930'LOCALLY KNOWN AS MONUMENT PEAK (COAST SURVEY NAME MOUNT PIERCE).
LV0930'PRACTICALLY EVERY ONE IN THE REGION IS FAMILIAR WITH THE LOCATION
LV0930'OF THE LAND SURVEY MARK AT THIS STATION.
LV0930'
LV0930'STATION MARK IS A CONCRETE MONUMENT AND 3 IRON RODS. MARKED
LV0930'BY THE U.S. LAND SURVEY. THIS POINT IS THE INTERSECTION OF
LV0930'THE PRINCIPAL MERIDIAN AND BASE LINE OF THE LAND SURVEYS OF
LV0930'NORTHERN CALIFORNIA.
LV0930
LV0930 STATION RECOVERY (1928)
LV0930
LV0930'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1928 (GLB)[G.L. Bean]
LV0930'STATION FOUND AS DESCRIBED EXCEPT SURFACE MARK DESTROYED.
LV0930'NEW SURFACE MARK SET IN HEAVY BOULDER ABOUT FLUSH WITH SURFACE
LV0930'OF GROUND. REFERENCE MARKS FOUND IN GOOD CONDITION. IRON
LV0930'RODS BENT OVER. A FAIRLY GOOD ROAD LEADS UP MONUMENT PEAK FROM
LV0930'THE REDWOOD HIGHWAY AT WILDWOOD. ABOUT HALF HOUR WALK FROM
LV0930'HIGHEST POINT OF ROAD UP OPEN RIDGE.
LV0930'
LV0930'THERE IS SOME DOUBT AS TO WHETHER OR NOT THIS IS THE SAME
LV0930'POINT USED BY LATHAM IN 1919.
LV0930
LV0930 STATION RECOVERY (1931)
LV0930
LV0930'RECOVERY NOTE BY CALIFORNIA GEODETIC SURVEY 1931
LV0930'FOUND THE THREE IRON RODS SET IN THE GROUND AND BENT TO THE
LV0930'N AS DESCRIBED IN THE RECOVERY NOTES OF G.L. BEAN IN 1928.
LV0930'
LV0930'THE REFERENCE MARKS NOS. 1 AND 2 WERE SET BY THE U.S.G.S.
LV0930'IN 1919 AND ARE IN PLACE AND IN GOOD CONDITION.
LV0930'
LV0930'THE DOUGLAS FIR TREES MARKED AS WITNESS TREES ON OCTOBER 6,
LV0930'1853 BY HENRY WASHINGTON, U.S. LAND SURVEYOR AND DESCRIBED AS
LV0930'FOLLOWS--
LV0930'
LV0930'37-INCH FIR N 4 DEG 30 MIN E, 669 LINKS MARKED T.1.N.R.1.E.S.31 X
LV0930'
LV0930'63-INCH FIR S 64 DEG 45 MIN W, 825 LINKS MARKED T.1.S.R.1.W.S.1. X
LV0930'
LV0930'WERE FOUND TO BE STILL LIVING AND IN THE RELATIVE POSITION
LV0930'AS DESCRIBED. THE SCRIBE MARKS WERE COVERED WITH A NEW
LV0930'GROWTH OF WOOD BUT THE OLD BLAZES AND X MARKS WERE QUITE
LV0930'VISIBLE.
LV0930'
LV0930'THE 37-INCH TREE NOW MEASURES 49 INCHES AND THE 63-INCH TREE
LV0930'NOW MEASURES 77 INCHES.
