GN0677.The horizontal coordinates were established by classical geodetic methods
GN0677.and adjusted by the National Geodetic Survey in December 1993.
GN0677
GN0677.The NAVD 88 height was computed by applying the VERTCON shift value to
GN0677.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
GN0677
GN0677.Significant digits in the geoid height do not necessarily reflect accuracy.
GN0677.GEOID18 height accuracy estimate available here.

GN0677 STATION DESCRIPTION
GN0677
GN0677'DESCRIBED BY US GEOLOGICAL SURVEY 1931
GN0677'FOLLOWING DESCRIPTION BY USGS, 1931
GN0677'
GN0677'ON HIGHEST POINT OF TSCHICEMA MOUNTAIN, 17 MI. W. OF ESPANOLA.
GN0677'ANIMALS CAN BE TAKEN TO STATION BY TRAIL FROM SANTA CLARA CANYON.
GN0677'TRAILS LEAD UP S. SIDE OF MOUNTAIN.
GN0677'
GN0677'LANGLEY, WAS DESCRIBED BY GEOLOGICAL SURVEY BUL. 122, PAGE 165,
GN0677'1882-90, AND IN 1906, H. L. BALDWIN, JR., IN TRIANGULATION OF THE
GN0677'PLATEAU REGION OF NEW MEXICO (1887) AS ON THE HIGHEST POINT OF TEWAN
GN0677'MOUNTAINS. THIS PEAK WAS CALLED --SANTA CLARA-- BY WHEELER SURVEY AND
GN0677'--LANGLEY-- BY GEOLOGICAL SURVEY. THE POINT WHERE THE SIGNAL MONUMENT
GN0677'NOW STANDS IS BELIEVED TO HAVE BEEN THE LOCATION OF THE OLD CUT-IN
GN0677'POINT AS THE REMAINS OF AN OLD MONUMENT ARE IN EVIDENCE.
