 QA0690.The horizontal coordinates were established by classical geodetic methods
 QA0690.and adjusted by the National Geodetic Survey in July 1992.
 QA0690.
 QA0690.The orthometric height was scaled from a topographic map.
 QA0690
 QA0690.Significant digits in the geoid height do not necessarily reflect accuracy.
 QA0690.GEOID18 height accuracy estimate available here.

 QA0690
 QA0690'DESCRIBED BY COAST AND GEODETIC SURVEY 1957 (WRH)
 QA0690'THE STATION IS LOCATED ABOUT 50 MILES AIRLINE SOUTHWEST OF
 QA0690'SALMON, 14 MILES AIRLINE WEST NORTHWEST OF CHALLIS, ON THE
 QA0690'CENTER ONE OF THREE CONE SHAPED PEAKS.
 QA0690'
 QA0690'THE U.S. FOREST SERVICE LOOKOUT HOUSE IS A 14 FOOT SQUARE
 QA0690'BUILDING ABOUT 10 FEET HIGH AND IS PAINTED WHITE.  IT HAS
 QA0690'A TWO GABLED ROOF PAINTED GREEN WITH 399 PAINTED ON THE
 QA0690'EAST SIDE.  THE CENTER OF THE HOUSE WAS TRAVERSED TO TWIN PKS
 QA0690'1957.
