01/01/1968 by CGS (MONUMENTED)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1968 (LGB) THE STATION WAS RECOVERED WITH ALL MARKS IN GOOD CONDITION ALTHOUGH A SMALL FROST CRACK WAS NOTED IN THE ROCK MARKING THE USGS STATION WHICH MAY EVENTUALLY SPLIT IT IN TWO. A NEW ROUTE WAS FOUND TO THE END OF TRUCK TRAVEL USING THE ROAD TO THE SUMMIT STATION OF THE JACKASS SKI LIFT ON WARDNER PEAK. MARK MEASUREMENTS PROBABLY DO NOT COMPARE BECAUSE OF LONG GRASS. A COMPLETE DESCRIPTION FOLLOWS-- THE STATION IS LOCATED 6-1/4 MILES WEST-SOUTHWEST OF OSBURN, 3-3/4 MILES SOUTH OF KELLOGG, ON THE HIGHEST POINT OF KELLOGG PEAK AND TOWARD THE EAST END OF THE SMALL FLAT AREA ON THE SUMMIT. TO REACH THE STATION FROM THE POST OFFICE ON DIVISION STREET IN KELLOGG GO SOUTH 0.1 MILE ON DIVISION STREET TO A DIAGONAL INTERSECTION. TURN RIGHT AND CONTINUE SOUTH ON DIVISION STREET 1.4 MILES TO A GRAVEL SIDE ROAD ON THE RIGHT AND SIGN SKI BOWL.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in July 1992.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
