I read in my guide book...
"Glacier Point
Walk to the edge and catch your breath along with one of the most spectacular overlooks on earth. From this perch on the rim of Yosemite Valley, you'll look down 3,214 feet to the Valley floor and have an eagle's view, an overlook, with a commanding view of Yosemite Valley, Half Dome and the High Sierra. It is located 30 miles (one hour) from Yosemite Valley. Take Highway 41 for fourteen miles to the Chinquapin junction, then turn left onto Glacier Point Road. The road ends at Glacier Point."
And now I'm here! Thank you, Jeff!
