ET0987	1919	S	CGS	CVH	STATION IS ABOUT 8 MILES AIR LINE AND 16 MILES BY ROAD AND TRAIL NNW OF PRESCOTT. IT IS ON THE HIGHEST PEAK OF GRANITE MOUNTAIN, ON A SHELVING FLAT ROCK AT THE S SIDE OF THE SUMMIT, AND 3 OR 4 FEET LOWER THAN SOME OF THE SURROUNDING CRAGS. STATION MARK IS A BRONZE DISK SET IN A DRILL HOLE IN OUTCROPPING BEDROCK. HEIGHT OF SIGNAL ABOVE STATION MARK - 1.25 METERS.
ET0987	1935	G	USFS	*	STATION IS ON HIGHEST, MOST RUGGED, SHARPEST, AND MOST PROMINENT PEAK IN THE LOCALITY. THIS MOUNTAIN IS WELL KNOWN LOCALLY AS GRANITE MOUNTAIN. STATION IS 8 MILES (AIR LINE) NNW OF PRESCOTT. STATION MARK IS A BRONZE STATION DISK SET IN GRANITE LEDGE ROCK AND IS STAMPED GRANITE 1919. STATION GRANITE (U.S.G.S.) IS 16.25 METERS DISTANT. TO REACH STATION FROM PRESCOTT, TAKE PRESCOTT-SKULL VALLEY ROAD NW APPROXIMATELY 7 MILES TO ALTO SIDING. THEN TAKE GRANITE BASIN ROAD N APPROXIMATELY 3 MILES TO GRANITE BASIN. THENCE BY TRAIL W TO TOP OF GRANITE MOUNTAIN AND END OF TRAIL. THENCE N TO HIGHEST POINT. ABOUT A 3-HOUR CLIMB FROM GRANITE BASIN.
ET0987	1944	G	CGS	EHB	STATION RECOVERED AND ALL MARKS FOUND IN GOOD CONDITION. AN ADDITIONAL REFERENCE MARK AND AN AZIMUTH MARK HAVE BEEN ESTABLISHED. STATION IS LOCATED ON GRANITE MOUNTAIN, A HIGH AND PROMINENT MOUNTAIN ABOUT 8 MILES NNW OF PRESCOTT. THE MOUNTAIN IS WELL KNOWN LOCALLY. STATION MARK IS A BRONZE STATION DISK SET FLUSH IN A LARGE BOULDER AND IS STAMPED GRANITE 1919. REFERENCE MARK 1 IS A BRONZE REFERENCE DISK SET FLUSH IN A LARGE BOULDER AND IS STAMPED GRANITE NO 1 1944. IT IS AT ABOUT THE SAME ELEVATION AS STATION MARK. REFERENCE MARK 2 IS GRANITE (U.S.G.S.). GRANITE USGS IS A STANDARD U.S GEOLOGICAL SURVEY BENCH MARK DISK SET IN A LARGE BOULDER THAT FORMS THE HIGHEST POINT OF THE PEAK. MARK IS NOT STAMPED. IT IS 16.252 METERS (53.318 FEET) ENE OF U.S.C. AND G.S. STATION GRANITE AND ABOUT 7 FEET HIGHER. AZIMUTH MARK IS A BRONZE AZIMUTH DISK SET IN OUTCROPPING BEDROCK AND IS STAMPED GRANITE 1944. IT IS 24 FEET E OF THE CENTER LINE OF ROAD AND ABOUT 5 FEET HIGHER THAN THE ROADBED. TO REACH STATION FROM PRESCOTT, TAKE LEFT FORK AT THE MILLER VALLEY SCHOOL FOR 2.9 MILES TO A RIGHT FORK AT WHICH IS A LARGE SIGN READING GRANITE BASIN RECREATION AREA. HERE TAKE RIGHT FORK AND CONTINUE FOR 1.6 MILES TO A FORKS, KEEP RIGHT AND CONTINUE FOR 0.5 MILE. AT THIS POINT A LARGE ROCK OUTCROP WILL BE SEEN TO THE RIGHT OF THE ROAD AND IT IS IN THIS OUTCROP THAT THE AZIMUTH MARK HAS BEEN PLACED. FROM THIS POINT CONTINUE 1.1 MILES TO A JUNCTION. CONTINUE STRAIGHT AHEAD ON GRADED ROAD FOR 0.9 MILE TO A WASH, CROSS WASH AND PASS THROUGH THE GATE AND CONTINUE FOR 0.1 MILE TO THE END OF TRUCK TRAVEL. THE PEAK CANNOT BE SEEN FROM THIS POINT. PACK TO THE RIGHT AROUND SOME LARGE ROCK CLIFFS AND THENCE THROUGH A SADDLE AND INTO A CANYON. FROM HERE A DEEP AND ROUGH CANYON CAN BE SEEN LEADING UP TO THE PEAK. PACK INTO THIS CANYON AND FOLLOW IT TO THE PEAK. THE STATION IS ABOUT 16 METERS WSW OF THE HIGHEST POINT AND IS IN A LARGE BOULDER WHICH BREAKS OFF SHARPLY TO THE S.
ET0987	1969	G	USGS	*	RECOVERED AS DESCRIBED BY NGS. REACHED BY HELICOPTER. POWER GROUND-HOLD LANDING CAN BE MADE ABOUT 100 YARDS E. OF STATION. TRAIL NOW LEADS UP MOUNTAIN ON NORTHWEST SIDE OF PEAK. GRANITE USGS--STANDARD TABLET, UNSTAMPED, CEMENTED IN DRILL HOLE IN GRANITE BOULDER ON HIGHEST POINT OF TOP, 4.1 FT ABOVE STATION MARK.
ET0987	20240320	G	INDIV	JAS	STATION, REFERENCE MARK, USGS MARK AND THE AZIMUTH MARK WERE FOUND IN GOOD CONDITION. ADJUSTED TO REACH FOLLOWS. TO REACH THE STATION FROM PRESCOTT, TAKE THE LEFT FORK AT MILLER VALLEY AND IRON SPRINGS ROAD ONTO IRON SPRINGS ROAD FOR 2.9 MI (4.7 KM) TO A RIGHT FORK AT GRANITE BASIN ROAD AKA FR 374. HERE TAKE THE RIGHT FORK AND CONTINUE FOR 1.8 MI (2.9 KM) TO A FORK, KEEP RIGHT AND CONTINUE FOR 0.3 MILE. AT THIS POINT A LARGE FLAT ROCK OUTCROP PROJECTING A FEW FEET WILL BE SEEN TO THE RIGHT OF THE ROAD AND IT IS IN THIS OUTCROP THAT THE AZIMUTH MARK HAS BEEN PLACED. THIS OUTCROP IS JUST SOUTH OF ACROSS THE ROAD FROM THE DRIVEWAY TO THE YAVAPAI CAMPGROUND. FROM THIS POINT CONTINUE 1.2 MI (1.9 KM) TO A JUNCTION OF A ONE WAY ROAD. CONTINUE ALONG THE ROAD TO THE PLAYA PARKING LOT. THE PEAK CANNOT BE SEEN FROM THIS POINT. PACK ALONG THE GRANITE MOUNTAIN TRAIL NUMBER 261 FOR 3.6 MI (5.8 KM) TO A WOODED BASIN AND SOCIAL TRAIL DIVERGING TO THE NORTHEAST. THE EASIEST WAY TO REACH THE STATION FROM HERE IS TO FOLLOW THE COMMON OFF TRAIL ROUTE THAT IS USED, WHICH CAN BE FOUND ON THE WEBSITE HIKEARIZONA. THE PREVIOUS DESCRIPTIONS OF THE MARKS LOCATIONS IN RELATION TO EACH OTHER ARE VALID.
