 HR2884.The horizontal coordinates were established by classical geodetic methods
 HR2884.and adjusted by the National Geodetic Survey in March 1994.
 HR2884.The horizontal coordinates are valid at the epoch date displayed above.
 HR2884.The epoch date for horizontal control is a decimal equivalence
 HR2884.of Year/Month/Day.
 HR2884
 HR2884.The NAVD 88 height was computed by applying the VERTCON shift value to
 HR2884.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 HR2884
 HR2884.The Laplace correction was computed from DEFLEC99 derived deflections.
 HR2884
 HR2884.The geoid height was determined by GEOID99.

 HR2884'DESCRIBED BY US GEOLOGICAL SURVEY 1952
 HR2884'LOCATED ABOUT 18 MI E. OF YOSEMITE VALLEY, 10 MI SSE. OF TUOLUMNE
 HR2884'MEADOWS RANGER STATION.  AT JUNCTION OF CATHEDRAL RANGE, RITTER
 HR2884'RANGE AND SIERRA CREST, ON HIGHEST POINT OF MT. LYELL.
 HR2884'
 HR2884'TO REACH FROM TUOLUMNE MEADOWS RANGER STATION, RIDE 4 MI E. AND
 HR2884'S. ON DONOHUE PASS TRAIL UP LYELL CANYON TO LYELL UPPER BASE
 HR2884'CAMP.  PACK UP TRAIL 15 MINUTES TO WHERE TRAIL TURNS E.  CONTINUE
 HR2884'S. UP CANYON FOLLOWING DUCK LINE 1 HOUR AND 20 MINUTES.  GO LEFT
 HR2884'UP SLOPE 2 HOURS SSW. ACROSS SNOW FIELD AND GLACIER TO BASE OF
 HR2884'ROCK BLUFF IN SADDLE BETWEEN MT. LYELL AND MT. MCCLURE THEN LEFT.
 HR2884'CLIMB BLUFF (ROPES ARE SUGGESTED TO TRANSPORT EQUIPMENT) AND GO
 HR2884'UP STEEP SLOPE TO HIGHEST POINT ON EAST END OF TOP AND STATION.
 HR2884'A 5-1/2 HOUR PACK.

 HR2884'NOTE--STATION LYELL WAS A TRIANGLE CHISELED ON FACE ON ROCK WITH
 HR2884'USGS CHISELED ABOVE.  AN OLD BRONZE TABLET WAS FOUND IN CAIRN BUT
 HR2884'NOT SET.  IT WAS IMPOSSIBLE TO SET THE NEW TABLET IN CENTER OF
 HR2884'OLD MARK.  THE NEW MARK IS 0.6 FT. E. OF OLD MARK IN TOP OF SMALL
 HR2884'BOULDER.
