HW3570.The horizontal coordinates were established by classical geodetic methods
HW3570.and adjusted by the National Geodetic Survey in April 1998.
HW3570
HW3570.The orthometric height was scaled from a topographic map.
HW3570
HW3570.Significant digits in the geoid height do not necessarily reflect accuracy.
HW3570.GEOID18 height accuracy estimate available here.

HW3570 STATION DESCRIPTION
HW3570
HW3570'DESCRIBED BY US GEOLOGICAL SURVEY 1956 (WRH)
HW3570'THE STATION IS LOCATED ABOUT 15 MILES AIRLINE SOUTH OF
HW3570'HARMAN, 6 MILES
HW3570'AIRLINE SOUTHWEST OF RIVERTON, ON THE SUMMIT OF SPRUCE KNOB, THE
HW3570'HIGHEST POINT IN WEST VIRGINIA.
HW3570'
HW3570'THE CAIRN IS A PILE OF SMALL STONES 10 FEET HIGH AND 20 FEET WIDE AT
HW3570'ITS BASE, WITH A POLE
HW3570'RISING 10 FEET FROM ITS CENTER. IT IS 426.7 FEET, (130.6) METERS
HW3570'NORTHEAST OF TRIANGULATION STATION
HW3570'SPRUCE (USGS). THE CENTER OF THE CAIRN WAS TRAVERSED TO.
